Work visas and migrant workers in the UK

03 Aug 2022

This briefing examines labour migration and work visas in the UK immigration system, before and after the implementation of the post-Brexit immigration system. It presents data on migrant workers, particularly people coming to the UK on work visas (sometimes known as work permits).

  1. Key Points
    • For most of the last two decades, the EU was the major source of work-related migration to the UK, particularly in jobs classified as low-skilled.
    • Work related migration from EU countries had already declined sharply before the post-Brexit immigration system was introduced.
    • After free movement ended at the beginning of 2021, take-up of the new immigration system was low and EU citizens made up only 8% of work visa applications (excluding frontier workers).
    • Non-EU work visa grants recovered in 2021 after a pandemic-induced decline.
    • The health and social work sector was the biggest contributor to growth in the number of non-EU Skilled Workers over the past decade; in 2021, 47% of Skilled Worker route visa grants were in the Health and Care subcategory.
    • The Seasonal Workers scheme—the only work visa explicitly designed to bring workers for low-wage work—issued just under 30,000 visas in 2021.
    • Most non-EU citizens who receive work visas leave within 5 years and do not settle in the UK permanently.
    • More international students now stay on to work in the more liberal post-Brexit immigration system than they did in the mid- to late-2010s, but the majority do not.
    • Indian citizens were the largest recipients of work visas in 2021, followed by Ukraine.
  1. Understanding the Policy

    Until the end of the post-Brexit transition period in 2020, work-related migration to the UK was governed by two different policy regimes. People from EU countries (plus EEA and Switzerland) could come to the UK to work under free movement rules, without applying for permission, while citizens of non-EEA countries required a work visa. ...Click to read more.

    From January 2021, the post-Brexit immigration system was implemented. Under the new system, EU and non-EU citizens both need to get work visas in order to work in the UK (except Irish citizens, who can still live and work in the UK without a visa). This means that the post-Brexit immigration system became much more restrictive for EU citizens. For non-EU citizens, the new system is less restrictive than the one that preceded it. The post-Brexit work visa system and these changes over time are explained in more detail in the Migration Observatory policy primer, The UK’s 2021 points-based system.

    As of 2021, there are three main categories of work visas in the UK: employer-sponsored, long-term work visas; unsponsored long-term work visas; and temporary work visas.

    Employer sponsored, long-term work visas
    Some work visas provide work authorization for several years, usually with the opportunity to apply for settlement after five years. Most people coming to the UK for work on a visa like this must be sponsored by an employer. The best known visa to do this is the Skilled Worker route (previously known as ‘Tier 2 general’), which is for employees in middle- or high-skilled jobs. Workers using this route must usually earn annual salaries of at least £25,600, but there are exceptions for some workers or jobs, including young people under the age of 26, people working in shortage occupations, and people in health and education jobs who are paid based on agreed pay scales. For example, nurses do not have to meet the £25,600 threshold. Workers in jobs on the shortage occupation list face a minimum salary of £20,480.

    Some workers qualify for the ‘Health and Care’ visa. This visa is effectively part of the Skilled Worker route, except with lower fees. In this briefing, we include Health and Care within the Skilled Worker category unless otherwise specified. In February 2022, care workers were added to the Skilled Worker route despite not meeting the skills threshold for the route. (They must still meet the shortage-occupation salary threshold of £20,480.)

    The other main group of skilled, sponsored workers is intra-company transferees. These are for staff who already work for an overseas office of an international company and are coming to the UK office, often on temporary assignments. Most intra-company transferees can remain in the UK long term but cannot apply for settlement unless they switch into another visa category first (small numbers of intracompany graduate trainees can stay up to 12 months only).

    In this briefing, we refer to these two groups together as ‘skilled sponsored workers’ (without capitalization, to distinguish it from the ‘Skilled Worker’ subcategory). For simplicity, we also use the term Skilled Worker route to refer both to the route in the post-Brexit system, and to its pre-2021 equivalent, Tier 2 (general).

    Unsponsored, long-term work visas
    Some workers do not have to be sponsored by an employer but still have a route to long-term settlement in the UK. Most of these are categorized together in the UK’s immigration statistics as ‘High Value’ work visas, and were known as ‘Tier 1’ under the pre-2021 immigration system. They include:

    • Global Talent: various groups of people including those who have been endorsed by specified organisations, such as the British Academy or Tech Nation; who have secured a job as a researcher or technical specialist at a research organisation; or who have received ‘prestigious prizes’ such as Oscars;
    • Entrepreneurs whose business ideas have been endorsed by one of a list of organisations including various accelerator programmes and early-stage investors.

    Another unsponsored long-term work visa is the ‘ancestry visa’. Commonwealth citizens with at least one grandparent born in the UK can also get a long-term visa to work here without employer sponsorship. There are no skills-based selection criteria. Similarly, the British National (Overseas) route allows certain people from Hong Kong to live and work in the UK long term; the visa was introduced in response to national security legislation in Hong Kong and is not explicitly a work visa, but it can be used to work without employer sponsorship.

    Temporary visas
    Various temporary visas are available for other groups of workers. Most of these were previously known as ‘Tier 5’ of the pre-2021 immigration system. While there are many different categories, among the largest are the Youth Mobility Scheme and the Seasonal Worker visa.

    The Youth Mobility Scheme (YMS), gives 2-year non-renewable work visas to people aged 18 to 30 from certain countries with which the UK has signed an agreement (Australia, Canada, New Zealand, Japan, South Korea, Taiwan, Hong Kong and Monaco). At the time of writing in 2021, no EU countries were included on the list, although the government has said that it would like to negotiate deals with EU countries to include them. YMS visa holders do not need an employer to sponsor them and are not tied to specific jobs. There are caps on visa numbers for each nationality, although the overall number of visas granted is well below the total number that are in theory available. In 2021, the caps were: 30,000 (Australia), 13,000 (New Zealand), 6,000 (Canada), 1,500 (Japan), 1,000 (Monaco), 1,000 (Taiwan), 1,000 (Hong Kong) and 1,000 (South Korea).

    The Seasonal Workers visa admits workers for up to 6 months, and had a cap of 40,000 places in 2022. This was up from 30,000 in 2021, 10,000 places in 2020, and 2,500 places in 2019. Usually Seasonal Workers must be working in horticulture, although in 2021 poultry workers, butchers and certain HGV drivers were temporarily added to the scheme.

    Another substantial but little-discussed temporary visa is for domestic workers in private households. This visa allows people who live abroad to bring cleaners, chauffeurs, cooks or carers to the UK with them for temporary visits of up to six months.

    Finally, temporary visas are available for graduating international students who want to remain in the UK after their studies to work. From 2008 to 2012, international students could apply for post-study work visas that gave them two years of work authorisation in any job. If they wanted to remain beyond this point they had to qualify for skilled work visas. International students graduating from UK higher education starting in the academic year 2020/21 can apply to stay on in the UK to look for and take on work at any skill and salary level, for up to two years (or three years for PhD graduates) before requiring another visa. This effectively reverses the rule change that eliminated the post-study work visa in 2012.

    In some cases, visas are strictly temporary and workers must leave the country when their visas expire, unless they are able to switch into another visa category. Most of the long-term visas described above, however, provide a route to settlement after five years. During the 2010-2015 Coalition Government, the Home Office had an explicit policy to break the link between temporary migration and permanent settlement (Home Office, 2011). This included a higher income requirement for Skilled Workers to access permanent settlement from April 2011 onwards. This policy was reversed in the post-Brexit immigration system, and most Skilled Workers now only need to maintain the original eligibility criteria for 5 years to become eligible for settlement.

    Low-wage work
    Except for Seasonal Workers and care workers, there are no employer-sponsored visas for workers taking up low-wage or low-skilled jobs. This means that unless the worker qualifies for one of the categories described above, such as the Youth Mobility Scheme, it is usually not possible for employers to sponsor workers to come to the UK in jobs that do not meet the skill and salary thresholds for skilled work visas. This includes jobs such as waiters and waitresses, cleaners and heavy goods vehicle drivers.

  1. Understanding the Evidence

    The Home Office provides information on visas issued to non-UK citizens to work in the UK. Unless otherwise specified, the visa data in this briefing only include people receiving their visas from outside the country. ... Click to read more.

    Visa data gives an indication of how many people are coming to the UK for work, although not everyone who is issued a visa will necessarily come to the UK – some change their plans after a visa is issued, and this was increasingly the case during the pandemic in 2020. Unless otherwise specified, the visa data in this briefing only include people receiving their visas from outside the country and not those who extend their visas in-country.

    This briefing also uses Home Office data on ‘Certificates of Sponsorship’ (CoS) for skilled sponsored work visas. When employers sponsor a worker, they must assign them a CoS. The worker then uses the CoS to apply for their entry visa to the UK. Again, some people who receive a CoS may not actually come to the UK.

    Until early 2020, a major source of information on work migration was the International Passenger Survey (IPS). While full year figures are available for the year ending December 2019, face-to-face interviews were suspended due to Covid-19 in March 2020 and since then there have been no new migration statistics based on the IPS.

    This briefing also uses data from the Annual Population Survey (APS). The APS is based on an ONS survey of households across the UK and provides detailed information on the characteristics of people living here—including whether their reason for coming to the UK was work. It has some important limitations, however. Some people are excluded, such as residents of communal establishments like hostels. Response rates for the survey have declined over time, and were particularly low during the pandemic; this means that there is added uncertainty about the reliability of the data for 2020. Because the APS is a sample survey, the estimates come with margins of error. This means that small differences between numbers or percentages may not be statistically significant – that is, they may not reflect real differences in the population. This briefing rounds APS estimates to the nearest 1,000, although in practice the margins of error will be much larger than this.

    Note that work visas are sometimes also referred to as ‘work permits’, although we use the term visa throughout this briefing. This briefing uses the term ‘migrants’ to refer to the foreign-born, and ‘migrant workers’ to refer to foreign-born people who are working; note that some will subsequently have acquired British citizenship.

    A note on terminology: when discussing policy, this briefing uses the term ‘EU’ for ease of understanding, but readers should note that citizens of non-EU countries Switzerland, Iceland, Liechtenstein and Norway also faced the same rules as EU citizens until the end of free movement. The official datasets used in this briefing do not include non-EU EEA or Swiss citizens in the ‘EU’ category; unless otherwise specified, these citizens are included in the ‘non-EU’ category, although in the case of visa data they will have received very few visas before 2021.

For most of last two decades, the EU was the major source of work-related migration to the UK

Work is an important driver of overall migration to the UK, alongside family and international study. On average from 2010 to 2019, 40% of migrants moving to the UK for at least a year said that their main reason for moving was work (ONS, 2020).

Before the EU referendum and the Covid-19 pandemic in 2020, free movement from the European Union was a major source of labour migration to the UK. By 2020, an estimated 55% of foreign-born workers who said that they had originally moved to the UK for work-related reasons were born in EU countries (Figure 1). This is largely the result of 15 years of migration from EU countries following EU enlargement in 2004.

A key feature of free movement rules that were in place until 2021 was that EU migrants could work in any job, whereas non-EU citizens on work visas would often have to meet skills-based selection criteria (see the Understanding the Policy section, above).

In part as a result, EU workers have been more likely to be working in low-wage jobs and less likely to be in high skilled jobs than non-EU workers. In 2020, an estimated 36% of non-EU born migrants were in jobs classified as highly skilled, for example, compared to 30% of the EU born (Figure 1). Among non-EU born workers, there are large differences depending on the reason for migration. Non-EU migrants who said that their main reason for coming to the UK was work were most likely to be in skilled jobs (45%), reflecting skill-based selection criteria for work visas. People who came to study—many of whom will subsequently have had to qualify for work visas in order to remain in the UK—also had high shares in skilled work. By contrast, EU-born workers who came for work were less likely to be in high-skilled jobs (27% in 2020).

Figure 1

Among workers who originally moved for work reasons, the EU born make up a lower share in London (46%) than the rest of the UK (60%). This reflects both London’s long-standing popularity with non-EU citizens, and the fact that EU workers after 2004 moved in large numbers to non-traditional destinations outside of London, including the East of England and East Midlands.

While the skill profile of non-EU born workers in London is broadly similar to the rest of the UK, EU-born workers were significantly more likely to be in high-skilled work if they lived in London (37%) compared to the rest of the UK (27%). This in part reflects the overall composition of London’s workforce, which has a higher share of high-skilled jobs—including among the UK born. Nonetheless, London still has a substantial low-wage EU migrant workforce. In 2020, the EU born made up an estimated 22% of workers in jobs classified as low-skilled in London, compared to just 10% in the rest of the UK (data from Figure 1). This means that while London is sometimes portrayed as being less affected by the end of free movement because of the higher salaries there, London employers have in fact relied more heavily on EU workers than other parts of the UK.

UK employers have relied particularly heavily on EU workers in some occupations in logistics, food manufacturing, and hospitality, as detailed in the Migration Observatory briefing Migrants in the UK Labour Market: An Overview and our report on Low Skilled Work Migration After Brexit.

The end of free movement thus represents a major shift in UK immigration policy. Several occupations where employers have relied heavily on EU workers are no longer eligible for work visas under the new system, including in hospitality and food manufacturing. (For more discussion of eligible and ineligible jobs, see the Migration Observatory’s policy primer on the UK’s 2021 Points-based System.)

Work related migration from EU countries had already declined sharply before the post-Brexit immigration system was introduced

In recent years, EU migrants’ role in work-related migration has declined. After the June 2016 referendum, long-term EU migration dropped even before any new policies restricting EU migration came into force (Figure 2). Possible explanations for this decline include the fall in the value of the pound, reducing the value of money earned in the UK compared to other EU countries; political uncertainty due to Brexit; and the fact that EU migration had been unusually high in the pre-referendum period and thus might be expected to have fallen anyway. For more information on EU migration, see the Migration Observatory briefing, EU migration to and from the UK.

Figure 2

Second, Covid-19 had a big impact on the EU workforce in the UK. EU employees suffered large job losses in 2020, particularly in London. By December 2020, the number of jobs held by EU migrants in the UK had fallen by 7%, much higher than the 3% seen among their UK counterparts (Figure 3). While job losses among UK employees took place mostly at the beginning of the pandemic (from March to May 2020), net job losses among EU citizens continued throughout the year. Despite a modest recovery in the first half of 2021, EU worker employment remained 6% below its pre-pandemic (December 2019) level. By contrast, non-EU worker employment was 6% higher.

Figure 3

Not all EU migrants who lost their jobs will have left the country. Because the pandemic also disrupted data collection, its impact on EU migration and the EU migrant workforce is uncertain. ONS has produced various estimates of EU migration but they are subject to large uncertainty. One ONS analysis suggested that there had been net out-migration of EU citizens in 2020 of 94,000, although a more recent publication using a different methodology estimated net emigration of 12,000 among EU citizens in the year ending June 2021. A separate ONS analysis estimated that the EU-born population (age 16 and above) fell by 107,000 in the year ending Q4 2020. While such figures would represent a small share of the total EU migrant population, it is a sharp reversal of years of steady net growth in the EU migrant population.

EU citizens’ demand for work visas during the first few months of the post-Brexit immigration system was low

After free movement ended in January 2021, newly arriving EU citizens faced a more restrictive immigration system with higher costs and administrative obstacles. Many EU citizens currently working in the UK are in jobs that do not qualify for long-term work visas. Before the system was implemented, the Home Office estimated that the new rules might thus reduce long-term EU work migration by around 70%, by restricting the number of jobs that are eligible for visas (see the Migration Observatory’s commentary, Calculating the Bill, for more details). There was also some evidence that employer sponsorship requirements would reduce migration among people who are in principle eligible, for example due to costs and administrative barriers (Sumption, 2019).

In the first year after free movement ended, approximately 34,000 EU citizens made work visa applications, making up only 13% of work visa applicants (including dependents) (Figure 4). This includes people coming for short work-related trips and not necessarily relocating to the UK. Indeed, more than a third of all work visa applications from EU citizens in 2021 were for Frontier Worker permits—a specific category designed for people who do not actually live in the UK but used to come to the UK for work before the end of free movement (see Hunt [2021] for an explanation of how these permits work). If frontier workers are excluded, approximately 21,000 EU citizens made up about 8% of work visa applications.

These are low numbers when considering that in 2019, even after EU work migration had already fallen substantially post-referendum, an estimated 79,000 EU citizens made up 45% of non-UK citizens immigrating for at least a year for work (see Figure 2, above). Visa figures are typically considerably higher than long-term immigration figures because they include short-term movers and people who apply but never come to the UK, although they do not include EU citizens who have previously lived in the UK and are returning to the country with status under the EU Settlement Scheme.

Figure 4

EU citizens made approximately 12,000 applications for long-term Skilled Worker visas in 2021 (including health and care visas), which represented only 9% of the total. The low share is partly driven by very low numbers of EU citizens applying to come to the UK in Health and Care jobs (820 people or 1% of the total in 2021, including dependents).

Not all of the reasons for low EU demand for work visas under the new immigration system will persist. The year 2021 was of course unusual, and the UK entered a third lockdown a few days after free movement ended. Economic turmoil and travel restrictions meant that one would expect many fewer people to use the system in early 2021 than would otherwise have been the case. It is also possible that numbers of EU visa applicants will increase as employers become more familiar with rules on how to sponsor them. However, the data available so far are certainly consistent with the idea that the post-Brexit immigration system has substantially reduced work migration from the EU.

Non-EU work-related migration largely recovered in 2021 after a pandemic-induced decline

Covid-19 had a significant impact on non-EU labour migration. Total work visa grants fell by 40% for main applicants in 2020 (Home Office, 2021), and ONS analysis suggests that many people who received work visas did not take them up or left the UK early (ONS, 2021b).

The impact of the pandemic varied depending on the type of work visa (Figure 5). Intra-company transfers fell most sharply, declining by 67% or over 18,000 visa grants to non-EU citizens from 2019 to 2020, and only slightly increased in 2021 (to just under 11,000 visa grants). Most people on intracompany transfer visas are in the IT sector (MAC, 2015, Table 6.3), and many of these jobs can be done remotely. Skilled Workers fell by 21% from 2019 to 2020, but rebounded to just under 60,000 grants to non-EU citizens in 2021—well above pre-pandemic levels (Figure 5)

“High value” visa grants, e.g. to investors and ‘innovators’ fell in 2020 but returned to pre-pandemic levels in 2021, although they make up a small part of the work visa system (2% of visas granted to non-EU citizens in 2021).

Young people moving to the UK under the Youth Mobility Scheme can work in any occupation so will include people in a range of skilled and less-skilled positions. Their numbers remained lower than pre-pandemic levels. The numbers of workers on this visa are driven by citizens of Australia and New Zealand, both countries with very low rates of Covid-19 infection and significant travel restrictions in 2020 and early 2021. The government has said that it would like to negotiate with EU countries to add more of them to the list of nationals eligible for YMS—a move that would create work additional work visas that have no requirement to be in high-skilled work—but at the time of writing in mid-2022 no agreements have been concluded.

Figure 5

Continuing its growth through the pandemic, seasonal agricultural workers receiving visas quadrupled to just under 28,000, following an increase in the cap from 2,500 in 2019 to 10,000 in 2020, and another to 30,000 in 2021. The cap for 2022 is 40,000.

In most cases, the declines in work visas issued in 2020 were driven primarily by very low levels in the second quarter of the year, during the period of the first lockdown. By the second quarter of 2021, non-EU citizens’ demand for work visas had returned to numbers relatively close to pre-pandemic levels, however. Across all work visa categories, 138,000 work visas were granted to non-EU citizens in 2021, similar to the 137,000 in 2019. Declines in some work visa categories, such as intracompany transfers, were offset by growth in two categories in particular: the Skilled Worker and Seasonal Worker routes. Skilled Worker route growth could result in part from the liberalization of policy towards non-EU citizens in the post-Brexit immigration system, though it could also simply reflect the continuation of the long-term trend of rising demand for non-EU workers. Indeed, much of the growth was driven by the health sector (see below), which was already a large user of work visas before the post-Brexit immigration system came into force.

The health sector accounted for a growing share of skilled sponsored work visas from 2014 to 2021

After the financial crisis depressed demand for work visas in 2009, the number of non-EU skilled employees receiving employer-sponsored work visas had risen steadily from 2012 onwards (Figure 6). This coincided with falling unemployment as the UK economy recovered from the late 2000s financial crisis. Increases in 2018 and 2019 were facilitated by the government’s decision to exempt doctors and nurses from the 20,700 cap on these visas that had been introduced in 2011. As noted earlier, visa grants dropped sharply during the pandemic in 2020, but rebounded in 2021.

Figure 6

The two largest industries using skilled sponsored work visas are health and IT. The increase in the number of work visas for non-EU citizens from 2011 to 2020 was driven most strongly by one sector, though: health (Figure 7). The health sector accounted for 34% of visa applications and extensions in 2021, up from 8% in 2011. Because these figures include in-country visa extensions and not just workers newly arriving from overseas, this percentage likely understates the dominance of the health sector in the past few years in particular. Separate data on visa grants suggest that for skilled workers applying from abroad (rather than extending their visas within the UK), Health and Care work visa holders made up 47% of the total (Immigration Statistics, Table Vis_D02).

Applications for skilled sponsored work visas in the health sector nearly doubled from 2019 to 2021, albeit interrupted by a much lower figure during the pandemic in 2020. The IT sector, on the other hand, remained slightly below 2019 levels in 2021 (Figure 7). Health professions in the UK have relied heavily on migrant workers over the past decades, including both people on work visa and those on other immigration routes such as family visas. In March 2019, for example, 29% of doctors and 18% of nurses working in NHS hospitals were non-UK nationals (ONS, 2019).

Figure 7

Over the past decade, EU workers coming to the UK under free movement rules have played a substantial role in the health workforce. In March 2019, EU citizens made up 10% of hospital doctors and 7% of hospital nurses (ONS, 2019, Figure 5). The NHS has been a major recruiter of non-EU migrant workers on work visas, but in 2021 sponsored very few EU health workers in the Health and Care category of the Skilled Worker route (as described above).

The Seasonal Agricultural Workers’ Pilot—the only work visa explicitly designed to bring workers for low-wage work—saw 29,600 visa grants in 2021

The Seasonal Agricultural Workers Pilot is the only work visa designed to allow employers to sponsor migrant workers in low-wage work. Usually, employer-sponsored workers must be in skilled jobs earning at least £25,600 (see the Understanding the Policy section above). This scheme was introduced in 2019, when nearly 2,500 issues were issued, in anticipation of the end of free movement. A similar scheme existed until 2013, when it was suspended on the basis that there would be a sufficient number of workers coming from EU countries, including from Romania and Bulgaria.

The cap for the Seasonal Workers scheme was 30,000 places in 2021—up from 10,000 places in 2020, and 2,500 places in 2019. Of roughly 29,600 visas that were issued, the majority (67%) were to Ukrainian nationals. Only 7% went to EU citizens. Research on seasonal agricultural workers in the UK has found that they can be vulnerable to exploitative practices, such as being given misleading information about the job, not receiving the minimum wage, or paying fees to be recruited (e.g. FLEX, 2021; Burcu et al, 2021)). Evidence of exploitation exists among both migrants with free movement rights and those on visas, although the risks may be exacerbated in the case of seasonal work-visa holders because they have fewer rights and usually cannot change jobs. A Home Office and DEFRA review of the scheme in 2019 identified concerns among some seasonal workers, including complaints of underpayment and mistreatment by managers.

Work-related migration is often temporary; most non-EU citizens receiving work visas leave the UK within 5 years

Some migrants who come to the UK for work stay for short periods, while others stay permanently and receive permanent status (settlement) or UK citizenship. Temporary migration can have economic benefits, for example because recently arrived migrants tend to have more positive impacts on public finances (see the Migration Observatory briefing on the Fiscal Impacts of Migration). However, it can also have negative impacts in communities by increasing population churn (Poppleton et al, 2013).

Most non-EU work migrants do not settle permanently in the UK and there is evidence that non-EU work-related migration has become more temporary since the mid-2000s. By the end of 2021, 27% of non-EU citizens who received work visas in 2016 still had permission to be in the UK (this includes both main applicants and dependents). This is down from 32% of those receiving work visas in 2006, by the end of 2011 (Figure 8). A majority of people with visas in the small, ‘high value’, category still to have permission to remain in the UK after five years, however. Women entering on skilled sponsored work visas (including dependents) in 2016 were also more likely than men still to have permission to be in the UK five years later, at the end of 2021: 38% vs. 30% (Home Office migrant journey data, age and sex summary table MJ_04).

Figure 8

A key change for EU citizens coming to work in the UK long-term under the post-Brexit immigration system from 2021 onwards is that their immigration status depends on remaining employed—at least until they accrue five years of continuous residence and successfully apply for permanent settlement. By contrast, free movement provided more flexibility to spend periods out of the country or out of work without losing the right to live and work in the UK.

The end of free movement also brings various new costs for EU workers who are eligible for work visas. This includes the Immigration Health Surcharge (a total of £3,120 for a single person over five years, and more if they are bringing family members). It also includes the cost of a settlement application, which almost tripled from 2010 to 2020 and stood at £2,389 in 2022—as detailed in the Migration Observatory briefing, Settlement in the UK. Some employers pay these fees on migrants’ behalf, however.

Available data suggest that under free movement rules, there was significant short-term migration for work among EU citizens. In the year ending June 2019, EU citizens made an estimated 93,000 short-term trips of 1-12 months for employment, for example (ONS Table STIM.01a). There was also substantial long-term and permanent movement. For more information on temporary migration, see the Migration Observatory briefing, Permanent or Temporary: How long do migrants stay in the UK?

Some non-EU international students stay on to work, but the large majority do not

The number of international students receiving work visas to stay on in the UK after their studies fell sharply after 2012, when the ‘post-study work’ route was closed. After 2012, students who wanted to remain in the UK to work either needed to find an employer willing to sponsor them for a skilled work visa, or needed to qualify for another type of work visa, for example as an entrepreneur. A rebranded post-study work visa known as the Graduate scheme was introduced in 2021 and had take-up similar to its predecessor (Figure 9). Just under 25,900 former students were granted one of these visas inside or outside of the UK in 2021.

Most international students from non-EU countries do not remain in the UK to work after their studies, however. In recent years, around 200,000 to 300,000 international students have enrolled in UK higher education each year, the large majority from non-EU countries (Walsh, 2021). For more information, see the Migration Observatory briefing, Student Migration to the UK.

Indian citizens were the largest recipients of work visas in 2021, followed by Ukraine

Among non-EU citizens on work visas, the top countries of origin vary depending on the visa type (Figure 10). Indian nationals are the largest nationality for skilled sponsored work visas, followed by Ukraine. The high representation of Ukrainians in the work visa system results from their participation in the Seasonal Workers scheme, discussed above. Indian, American and Chinese citizens received the largest numbers of ‘High Value’ visas, while Australian citizens received the largest share of Youth Mobility visas in the same year. Overall, Indian citizens received 21% of all main applicant work visas in 2021.

Evidence gaps and limitations

Despite significant improvements in data on work-related migration over the past decade, there is still relatively little data on the economic outcomes and trajectories of work visa holders after they arrive. Published statistics provide data on the nationalities and, in some cases, proposed occupation and industry of work visa recipients when they apply for a visa or an extension. But little is known about how work visa holders fare in the long term, particularly after they have received settlement or citizenship (for those who remain in the UK). It is possible that in future such data could become available from administrative data sources (i.e. HMRC and DWP records).

There is also no data on the occupations or earnings of short-term migrants, particularly those from EU countries during the period when free movement was still in place. Short-term workers from either EU or non-EU countries are not expected to be captured well by the Labour Force Survey, which is currently the main source of information about migrant workers’ economic activity in the UK. This will make it difficult to analyze the impact of changes to the immigration system, which is likely to reduce the feasibility of many types of short-term work migration (due to the cost and restrictions associated with work visas).

Another area of limited evidence is emigration. While there were overall statistics on the numbers of people leaving the UK for at least 12 months (at least until 2019), it is currently not possible to provide a clear picture of the skills and activities of people who leave vs. remain in the UK long term.
