The Skilled Worker visa is the UK's main work route. It lets an employer with a sponsor licence hire someone from outside the resident labour market for an eligible job, and it counts towards settlement after five years.
You need a genuine job offer from a Home Office licensed sponsor for a role on the list of eligible occupations, at the required skill level.
Your pay must meet the higher of the general salary threshold and the going rate for your occupation code. Lower thresholds can apply if you are a new entrant, hold a relevant PhD, or the role is on the Immigration Salary List. Use the salary checker to compare an offer against the current figures.
After five years of continuous residence on the route, paid at or above the settlement salary, you can apply for Indefinite Leave to Remain, then British citizenship a year later. Keep your absences within the 180-day rule throughout.
