UK immigration authorities and sources of immigration law

Copyright © 2025 LexisNexis

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

ILPA publishes position statement on Mazur judgment implications for immigration practitioners

The Immigration Law Practitioners' Association (ILPA) has published a position statement responding to the High Court's judgment in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB), which confirmed that conducting litigation is a reserved legal activity under the Legal Services Act 2007 that cannot be delegated or exercised under supervision. The judgment has created uncertainty for immigration and asylum practitioners, particularly those accredited under the Law Society's Immigration and Asylum Accreditation Scheme (IAAS) or qualified through CILEX without formal litigation practice rights. ILPA notes that this judgment reinforces existing law but has significant implications for immigration and asylum practitioners, given that the sector has long relied on well-established accreditation and supervision frameworks to ensure competence and ethical practice. The position statement notes that CILEX Regulation issued interim guidance in October 2025 confirming individuals without litigation practice rights may support but not conduct litigation, while the Legal Services Board has approved CILEX Regulation's application for standalone litigation practice rights. The Law Society has confirmed that IAAS accreditation does not constitute authorisation to conduct litigation under the Legal Services Act 2007.

House of Commons Library publishes briefing on immigration and ECHR legal framework

The House of Commons Library has published a research briefing examining the European Convention on Human Rights (ECHR) framework in UK immigration law. The briefing reports that from 2015 to 2024, around 61,000 ECHR appeals succeeded in the first-tier immigration tribunal. Despite media coverage highlighting appeals by criminals specifically, successful challenges by foreign criminals represented approximately 3% of completed deportations for criminal offending. The document outlines current legal provisions under Articles 3 and 8 of the ECHR, including different deportation tests based on sentence length and various exceptions within immigration rules. The briefing notes that the current government is conducting an internal review of ECHR implementation, with then Home Secretary Yvette Cooper stating that around 30% of immigration decisions are being treated as 'exceptional' under ECHR interpretations. The briefing reports that the May 2025 immigration white paper promised legislation to strengthen the public interest test and clarify Article 8 rules to reduce cases treated as exceptional. The briefing also documents the historical development of ECHR immigration rights from the 1985 Abdulaziz case through to recent Supreme Court decisions.
