Immigration enforcement and immigration officer roles

Immigration officer roles in the Home Office fall into three main groups: enforcement officers who find and arrest people in breach of immigration law and arrange their removal, criminal investigators who pursue organised immigration crime, and caseworkers in UK Visas and Immigration who decide asylum and visa applications. Most frontline posts are at EO grade, with HEO for senior and specialist roles. Pay is set by the Home Office, security vetting is required, and some posts are restricted to UK nationals.

Three parts of the Home Office

The titles can be confusing, so here is who does what. Border Force works at the border itself, checking people and goods arriving at ports and airports; our Border Force officer guide covers it. Immigration Enforcement works inland, dealing with people who are in the UK without permission and with the organised crime that facilitates illegal migration. UK Visas and Immigration (UKVI) handles applications: visas, asylum claims, settlement and citizenship.

Each has its own recruitment campaigns, though they all sit in the same department. Our guide to Civil Service departments and agencies shows where the Home Office fits.

Immigration Enforcement officers

Arrest teams, often called immigration compliance and enforcement teams, visit homes and businesses where intelligence suggests immigration offenders are living or working illegally. Officers make arrests, conduct interviews, check documents and process people into detention or reporting arrangements. Other teams manage people who report regularly to the Home Office, handle detention casework, arrange removals and escorts, or work with employers on illegal working.

The job involves early-morning operations, forced entry in some cases, and confrontations. Officers must pass personal safety training, and fitness standards may apply for arrest team posts. Shift work and unsocial hours are common, with allowances paid where the role qualifies.

Criminal and Financial Investigation teams investigate people smuggling, sham marriages, document fraud and other organised immigration crime. These are typically HEO or higher posts, often filled by people with police or investigation backgrounds, and they work to criminal evidence standards.

Caseworkers and decision makers

UKVI employs large numbers of caseworkers and decision makers, most at EO grade. Asylum decision makers interview claimants about their reasons for seeking protection, research country information, assess credibility against the law and policy, and write a reasoned decision. Visa and settlement caseworkers check applications against the Immigration Rules, request evidence, and grant or refuse.

The decisions affect people’s lives directly, and refusals can be appealed. Asylum interviews in particular can involve accounts of torture, violence and loss, so the work is emotionally demanding. Ask at interview about caseloads, quality checks, and the support available after difficult interviews. Our profile of the executive officer grade covers how the grade works across the Civil Service.

Nationality, vetting and checks

Under the Civil Service nationality rules, UK nationals can apply for any post, and around 75% of posts across the Civil Service are also open to Commonwealth citizens and EEA nationals. Reserved posts, which involve national security, are open to UK nationals only. Some enforcement and investigation roles may fall into this category, and the advert says which rules apply.

Security vetting is set at a level for the post, can take time and may need a period of UK residence. Enforcement posts usually require a medical, and many need a full driving licence.

Pay and pension

The Home Office sets its own pay ranges for each grade. Adverts show the starting salary, often with separate London and national rates, and enforcement roles may add an allowance for shift work or operational duties. For 2026/27, the Civil Service pay remit guidance allows departments to increase their paybill by up to 3.5%, and states that this does not confirm any individual’s rise.

You join the alpha pension scheme. In 2026/27 members pay 4.6% on pensionable pay up to £36,199 and 5.45% from £36,200 to £56,000.

Getting through recruitment

Home Office campaigns run on Civil Service Jobs, often in large rounds for caseworkers. The process usually includes an online application with behaviour examples, online tests, and an interview mixing behaviour and strengths questions. Making Effective Decisions, Communicating and Influencing, Delivering at Pace and Working Together are common. Our guide to Civil Service behaviours shows how to write examples that score well.

After an offer you complete foundation training, which includes the legal framework, interviewing and the systems, plus training in arrest and safety techniques for enforcement roles. Officers have to be designated before using immigration powers, and you work under supervision until you are signed off.
