How UK visas work: a plain-English guide
Key facts
- Every UK visa is set out in the Immigration Rules, which the Home Office changes several times a year.
- Most work and study routes use a points-based system: a sponsor, a skill level, a salary and English.
- You can often switch between routes inside the UK, but not from a visitor visa or most short-term routes.
- Most long-term routes lead to settlement (ILR) after 5 years, then citizenship 12 months later.
- Fees rise regularly. Most long visas also carry the Immigration Health Surcharge of £1,035 a year.
How the UK visa system works
UK immigration law is mostly set out in the Immigration Rules, a document the Home Office updates through statements of changes, usually several times a year. Each route, from visitor visas to indefinite leave to remain, has its own part of the Rules with its own requirements for eligibility, evidence, money, English and suitability.
Applications are made online and decided by UK Visas and Immigration. Most applicants also give biometrics at a visa centre or use the ID check app, pay a fee and, for longer visas, the Immigration Health Surcharge. Caseworkers decide on the evidence you send, so missing or inconsistent documents are among the most common reasons for refusal.
The points-based system
Work and study routes use a points-based system. Rather than adding up flexible points, most routes have mandatory requirements that each carry points: a job offer or place from a licensed sponsor, a role or course at the right level, a minimum salary or enough money to support yourself, and English at the required level.
Sponsors hold licences from the Home Office and take on legal duties, such as reporting changes and keeping records. Some routes, such as Global Talent and High Potential Individual, need no sponsor and use an endorsement or a qualification instead.
Switching visas inside the UK
Many people can switch from one route to another without leaving the UK, for example from Student to Skilled Worker, or from Skilled Worker to a partner visa, if they meet the new route’s requirements. You must usually apply before your current permission expires.
Some routes do not allow switching inside the UK. Visitors, short-term students and most short-term work routes generally need to apply from abroad. If your current permission is close to expiring, apply in time, because a gap can affect future applications and settlement.
Routes to settlement and citizenship
Indefinite leave to remain (ILR) means you can live in the UK without time limits. Most long-term work, family and some business routes lead to ILR, usually after five years on the same route; others count ten years’ continuous lawful residence across different visas. Settlement needs the Life in the UK test and English, and continuous residence with absences inside the limits.
Once settled, most people can apply for British citizenship after a further 12 months, or straight away if married to a British citizen. Citizenship is discretionary, and good character, absences and past immigration breaches are all considered.
What’s changed recently
- The government has proposed longer qualifying periods for settlement on many routes. We confirm the current position for each case.
- A new Home Office fee schedule took effect, with increases to many application fees.
- Skilled Worker salary and skill thresholds were raised, and the care worker route on the Health and Care Worker visa closed to new overseas applicants.
- The Electronic Travel Authorisation was extended to most visa-free nationalities.
