The UK runs an independent Points-Based Immigration System with a route per migration purpose, each with its own salary or qualification threshold, sponsor requirements, and visa fee. Choose the route first; everything else flows from it.
The Points-Based System in one paragraph
The main routes for third-country nationals:
- Skilled Worker — employer-sponsored work visa; salary threshold (around £38 700/year as of 2026 for most roles, with route-specific going rates) plus English language requirement; tied to a Sponsor Licence holder
- Health and Care Worker — for eligible medical, care and social care roles; lower salary floor, IHS exemption, faster processing
- Student — tied to a Confirmation of Acceptance for Studies (CAS) from a licensed sponsor institution; financial maintenance proof required
- Graduate — post-study work permit of 2 years (3 for PhDs) after a UK degree, no employer required; an unsponsored bridge into the labour market
- Global Talent — for endorsed leaders or potential leaders in academia, research, arts, digital tech; no salary threshold, employer-independent
- High Potential Individual (HPI) — for graduates of a small list of top global universities within 5 years of graduation, 2 years unsponsored
- Innovator Founder — for founders of innovative, viable, scalable businesses with an endorsed plan
- Family — for partners and dependants of British citizens or settled persons; the Minimum Income Requirement (MIR) applies to the sponsor
Each route has its own fee schedule, IHS multiplier and English-language test. Fees and thresholds change frequently — the canonical numbers are always on gov.uk, not in third-party guides.
Where to look officially
The single canonical hub is gov.uk/browse/visas-immigration, which links to every route, the application portal, fee tables and processing times. UK Visas and Immigration (UKVI), part of the Home Office, is the executive agency. For diploma recognition, ECCTIS (formerly UK NARIC) at ecctis.com issues the Statement of Comparability that UK employers and universities ask for. Regulated professions (medicine, nursing, law, teaching, engineering) sit with their own bodies — GMC, NMC, SRA, GTC, Engineering Council — each with its own assessment route.
What's substantially different from EU mechanics
Even when the vocabulary looks familiar, the mechanism often is not:
- Immigration Health Surcharge (IHS) of around £1 035/year/person paid upfront in addition to visa fees — there is no EU equivalent; in EU member states health insurance is contributory, not a one-off migration tax
- eVisa replacing the BRP since 2024-2025 — your status is online-only, accessed through a UKVI account, with share codes for verification; physical residence cards are being phased out
- Right-to-Rent and Right-to-Work checks are statutory obligations on landlords and employers, not just a paperwork formality, and apply at every new contract
- Sponsor Licence system — Skilled Worker visas only work through licensed employers, and the public register is where you check before applying
- Common Travel Area with Ireland, but no Schengen access — UK visas do not allow onward travel into the EU; treat the UK as a single-country destination for visa purposes
