About

Description

This codelist represents a list of codes indicative of a specific immigration status (e.g. indefinite leave to remain, asylum seeker awaiting decision).

Methodology

Search strategy This codelist was created by searching for the following terms and then selecting codes that were relevant to this aspect of migration status:

  • asylum
  • citizenship
  • dependant visa
  • immigra
  • indefinite leave
  • refugee
  • spouse visa
  • visa
  • work permit
  • overseas

Updated to include codes related to the Immigration Removal Centre Assessment Toolkit, based on discussions with two GPs and the rationale that individuals held in IRCs are likely to be either seeking asylum or undocumented. GP review: 5/02/25

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
