The Home office have produced a May 2018 user guide (pdf) to their statistics. This resource provides figures on the levels and trends in numbers of people who are covered by the UK’s immigration control and related processes.
The aim of this resource is to give an overview of the work of the Home Office, including that of UK Border Force and UK Visas and Immigration, and other government departments and agencies dealing with immigration.
This resource will help inform users including the government, Parliament, the media and the wider public; and to support the development and monitoring of policy.
The report finds:
- All people admitted are subject to immigration control except British, other European Economic Area (EEA) and Swiss nationals
- Individuals seeking to enter the UK are required to satisfy a Border Force Officer that they meet the relevant criteria for entry or admission, as defined under the Immigration Rules or the European Economic Area Regulations 2016 (EEA Regulations 2016)
- Detention may be used whilst identity and basis of claim are established, where there is a risk of absconding, as part of fast-track asylum procedures, until 2 July 2015 (in the case of straightforward asylum claims that can be decided quickly) and in support of the return of failed asylum seekers and others who have no legal right to be in the UK
- Individuals seeking to enter the UK must satisfy a Border Force Officer that they meet the relevant criteria for entry, as defined under the Immigration Rules drafted in accordance with the Immigration Act 1971 (as amended). In order to comply with this requirement, passengers must present themselves, on arrival at a port of entry, to a Border Force Officer.
