This article updates on our progress towards developing a better understanding on student migration to and from the UK since the November 2016 update.
We published two papers1 in 2016 that described what the statistics show on international student migration and potential reasons for the difference between long-term immigration of international students and those who subsequently emigrate after their studies. In addition, we published a paper2 in February 2017 on wider plans to make better use of data sources across government to inform public and policy debate on international migration, including international student migration.
ONS and other government departments are working together on a continuing programme of research to better understand what international students do after their studies and this article provides an update on progress made since the last published update in November 2016.
Latest provisional figures3 show that in the year ending September 2016:
long-term immigration to the UK was 596,000 and long-term emigration was 323,000; net migration was therefore 273,000
long-term immigration for study was 126,000 (87,000 were non-EU nationals)
long-term emigration for former students was 62,000 (41,000 were non-EU nationals)
If all international students emigrated from the UK after their studies and immigration for study was remaining at similar levels, then we’d expect the immigration and emigration figures to be similar. Therefore, there’s a demand for more detailed information to explain the difference between these two flows.
Notes for: About this article
(i) Population Briefing: International Student Migration – What do the statistics tell us? (January, 2016) (ii) An update on international student migration statistics (November 2016)
ONS International Passenger Survey figures on long-term international migration (based on the UN definition of someone changing their country of residence for one year or more).
Our work since November 2016 has looked at:
how the International Passenger Survey (IPS) identifies departing international students
what Home Office visa statistics are available to explain the difference
producing a conceptual diagram to describe more fully what non-EU students may do at the end of their studies
There is, however, no single data source that records all possible outcomes for international students after they’ve completed their studies, which can answer the question “what do students do after their studies if so few are emigrating?” However, for non-EU national students (around 70% of total student immigration), data are published in the Home Office Immigration Statistics Quarterly Release on grants of extensions to stay by visa category and nationality. Additional analysis is available from the Home Office publication “Statistics on changes in migrants’ visa and leave status: 2015” (formerly known as “The Migrant Journey”), which shows how non-EU nationals changed their immigration status, and the immigration routes used prior to achieving settlement in the UK.
Home Office data1 also provide information on the numbers of non-EU nationals previously on a study visa who switched their visa type for work, family or other (non-study). Therefore, it’s possible that some of these former students also appear in the IPS departure figures.
Does this help explain the “gap” between the immigration and emigration figures for students? It will help explain some of the gap. However, it can’t fully explain the gap because the number of students completing their courses in any particular year won’t match the numbers immigrating unless immigration levels are steady and all courses are the same duration, which isn’t the case. Therefore, if precise figures were available on all outcomes of those students who have finished their studies, there’s likely to still be a gap (and in some years the immigration figures could be theoretically lower).
Notes for: Our research so far

Figure 1 shows the different outcomes for non-EU international student immigrants after they’ve completed their studies. It shows where data sources are available; where they’ll become available; and the outcomes for students that may not be possible to measure with existing or planned data sources. It is provided for illustrative purposes only, since the inter-relationships between these sources are often complex and some students may appear on more than one overlapping source.
There are some outcomes that are likely to be explained as new data sources become available (for example, Home Office “exit checks” data); and some outcomes that may not be possible to measure with existing or even new data sources (for example, where international students may have left via the Common Travel Area or where there is no evidence of departing).
During 2017, we will continue working closely with other government departments to assess and develop new analyses based on administrative data sources. This includes:
collaborative analysis with the Home Office of its visas, Migrant Journey and "exit checks" data (introduced by the Home Office in April 2015); these data are likely to provide evidence relating to departures of some non-EU nationals who previously had study visas
linkage of HM Revenue and Customs’ PAYE data with Higher Education Statistics Agency (HESA) course completions data; these data will provide evidence of students remaining in the UK to work after completion of their studies, which will be particularly useful for EU nationals who are not included in Home Office visa data
linking HESA data on course completions in one year with new course enrolments in other years; for consecutive years, this will provide evidence of international students continuing to study in the UK following their initial courses (e.g. completing an undergraduate course and then enrolling on a postgraduate course)
analysis of cohorts of students, including evidence of their departure from the UK
In addition, in collaboration with the Centre for Population Change and Universities UK, we’ve launched an online international student survey to provide further information on international students’ post-study intentions; how sure they are of these intentions; their travel patterns whilst studying; use of public services; and working patterns whilst studying.
We will continue to identify how sharing, linking and exploiting other sources of data can help produce more detailed analysis of the impact of international migration on the economy and public services.
We plan to publish a further update in August 2017 to include the provisional results of this experimental work.
