UK immigration authorities and sources of immigration law

This topic looks at the legal framework that underpins UK immigration control and the government department that manages it.

Home Office

The Home Office is responsible for all aspects of control of the UK border and of the entry and stay of foreign nationals who require leave (permission) to enter and remain in the UK.

Any decision to grant or refuse leave to enter, entry clearance or leave to remain is made by the Home Office on behalf of the Secretary of State for the Home Department (SSHD). The Home Office also considers applications for British citizenship. Passport applications are handled by a separate part of the Home Office, His Majesty's Passport Office.

The immigration control work of the Home Office is split into three areas:

  1. UK Border Force—which manages applications for leave to enter at the border and customs functions

  2. UK Visas and Immigration—which deals with applications for entry clearance and leave to remain, asylum applications, appeals and sponsor management for the Worker, Temporary Worker and Student immigration routes

  3. Immigration Enforcement—which is responsible for investigating immigration offences, detention, administrative removal

Home Office revises all principal Sponsor Guidance documents

On 6 March 2026 the Home Office brought into force version 03/26 of the principal sponsor guidance documents within the ‘Workers and Temporary Workers: guidance for sponsors’ collection, together with consequential amendments to the route-specific guidance for Skilled Workers. The changes affect Part 1: Apply for a licence, Part 2: Sponsor a worker, Part 3 (compliance and enforcement), Appendix D (record-keeping guidance) and the ‘Sponsor a Skilled Worker’ guidance, and also see the introduction of a new standalone and expanded Glossary. There is now extensive cross-referencing across all documents to that centralised source of definitions. Across the suite of guidance, the concept of a ‘genuine vacancy’ or ‘genuine employment’ has been removed and replaced with the newly defined term ‘eligible role’. This definition, now embedded in the Glossary and incorporated expressly into the other guidance documents, requires that the role must exist or be reasonably anticipated, meet all route-specific requirements including skill level and salary thresholds, comply with wider employment legislation and remain appropriate to the sponsor’s business throughout the period of sponsorship. References to assessing whether a vacancy is ‘genuine’ have been systematically replaced with consideration of whether the work meets the definition of an ‘eligible role’ and refusal, suspension and revocation provisions have been redrafted accordingly.  Other changes include Parts 1 and 3 now making explicit that sponsorship is voluntary, that a licence is granted at the discretion of the Home Office and creates no enforceable right and now stating that enforcement action may be taken on the basis of ‘reasonable suspicion’ of non-compliance rather than established breach. Further details of the changes will follow.
