This release replaces the previous annual and quarterly publications Control of Immigration Statistics and the annual British Citizenship, following a public consultation. Each topic now has its own entry, links to these related reports can be found under the "additional links" section.
There are a range of measures that can be used to understand trends in immigration to the United Kingdom for work, for those people who are subject to immigration control. These include: issues of visas for entry clearance, providing information about those intending to come to the United Kingdom for work; work-related admissions data, providing information on migrants at the border; number of people allocated national insurance numbers, giving an indication of migrants entering the labour market; and
estimates on non-EU immigration from the International Passenger Survey on migrants intending to stay for at least a year for work purposes. In addition, grants of (in-country) extensions of stay for work purposes provide information on migrants in-country, while work-related grants of settlement provides a measure of longer term migration.
