  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

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

  3. 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
