Immigration Statistics: work

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.

本版发布替代了之前的年度及季度出版物《移民统计控制》及年度《英国公民身份》，此举基于公开咨询的结果。每个主题均拥有独立条目，相关报告的链接可在“附加链接”部分找到。为理解前往英国工作移民的趋势，可采取一系列措施，包括：入境签证清关问题，提供有意前往英国工作人士的相关信息；与工作相关的入境数据，提供边境移民信息；分配国家保险号码的人数，以此作为移民进入劳动市场的指标；以及国际旅客调查中对非欧盟移民的估计，该调查涉及有意至少工作一年的移民。此外，基于工作目的在境内延长停留期限的许可提供了境内移民的信息，而与工作相关的定居许可则衡量了长期移民的趋势。
