Your student visa allows you to work in the UK, but with limits. Understanding the rules protects your visa — breaking them is a serious immigration offence that can result in deportation and a ban on returning to the UK.
During term time you can work a maximum of 20 hours per week. This includes all paid work combined — if you have two jobs, the total across both cannot exceed 20 hours. During official university vacation periods (summer, Christmas, Easter) you can work full-time with no hour limit. Check your university's term dates carefully — the vacation definition used by the Home Office matches your university's official term calendar.
You can do most types of work: part-time jobs in retail, hospitality, tutoring, admin. You cannot: be self-employed or run your own business, work as a professional sportsperson or entertainer, or work as a doctor or dentist in training (without specific permission). Working through a staffing agency is fine as long as hours are within the limit.
You need a National Insurance (NI) number before starting paid work. You can start work before you receive your NI number but you must have applied for one. Without an NI number your employer cannot deduct the correct tax. Apply online via gov.uk — you'll need your passport and visa details.
Your employer must check your right to work before you start. You'll need to show your passport and either your visa vignette (sticker in passport) or your eVisa via the UKVI online share code service. Generate a share code at gov.uk/prove-right-to-work — it's valid for 90 days and lets your employer verify your visa status online.
Working more than 20 hours during term time is a visa condition breach. Consequences can include: visa curtailment (cut short), removal from the UK, and a 10-year ban on returning. Your university may also be notified. This is not a grey area — the Home Office takes it seriously.
Keep a simple weekly log of your hours — a notes app or spreadsheet is fine. If you work for multiple employers, track them all together. If your employer asks you to work more than 20 hours in a term-time week, explain your visa restriction — a good employer will understand and work around it.
