Student Visa Do's and Don'ts 2026 — What Gets Students Deported
Every year, thousands of international students lose their visas for breaking rules they didn't fully understand. This guide covers the critical do's and don'ts for student visas in Canada, UK, Australia and USA — the things that actually get students deported.
🌍 Universal Rules — Every Country
The most deported-for violation globally: working more hours than your visa allows. Immigration officers monitor tax records, employer records and social media. Getting caught working illegally does not just cancel your visa — it can result in a multi-year ban and deportation.
🇨🇦 Canada — Student Visa Rules
✅ DO: Work maximum 24 hours per week during academic session. Unlimited hours during scheduled breaks (Christmas, summer). Keep all pay slips. File Canadian taxes even as a student.
❌ DON'T: Accept cash-in-hand work. "Cash jobs" (restaurants, construction, cleaning) that pay off the books are still subject to the 24-hour limit. "I was paid cash" is not a defence if you are found working illegally.
❌ DON'T: Change institutions without updating your study permit. If you leave your DLI and join another without updating IRCC, you are in violation of your permit conditions.
❌ DON'T: Study at a non-DLI institution. Only Designated Learning Institutions are authorised. If your college loses DLI status, you must transfer immediately.
⚠️ WARNING: CBSA does check. Canada Border Services Agency has access to CRA tax records, employment data and can verify your work history at any port of entry.
🇬🇧 UK — Student Visa Rules
✅ DO: Work maximum 20 hours per week during term time. Full time during official university holidays. Any job type is permitted — retail, hospitality, office work, all fine.
❌ DON'T: Work more than 20 hours in any single week during term. Even one week of 21 hours is technically a violation. UK Home Office compliance checks are rigorous — universities report students.
❌ DON'T: Work as self-employed or set up a business without permission. Student visas in the UK specifically prohibit self-employment.
❌ DON'T: Miss your CAS expiry. The Confirmation of Acceptance for Studies (CAS) must be used within 6 months. Expired CAS means you cannot enter the UK.
🇦🇺 Australia — Student Visa Rules
✅ DO: Work maximum 48 hours per fortnight during term. This is 24 hours per week on average. Unlimited during official course breaks.
❌ DON'T: Count your hours loosely. The 48-hour fortnight limit is strictly enforced. Australian Border Force conducts workplace raids — particularly targeting restaurants, farms, and construction sites where student overstaying is common.
❌ DON'T: Fail the Genuine Student (GS) assessment. Australia can cancel your visa if they believe you are no longer genuinely enrolled and studying. Attend all classes. Maintain academic progress.
🇺🇸 USA — F-1 Visa Rules
❌ DON'T: Work off-campus without authorisation (CPT/OPT). F-1 students may only work on-campus for 20 hours/week during term, or off-campus through Curricular Practical Training (CPT) or Optional Practical Training (OPT) specifically authorised by USCIS. Unauthorised work is an immediate SEVIS termination.
❌ DON'T: Let your I-20 expire. You must maintain a valid I-20. If your programme extends, update your I-20 before the current one expires. An expired I-20 puts you out of status.
❌ DON'T: Transfer schools without authorisation. F-1 students must notify the DSO (Designated School Official) and transfer SEVIS records before attending a new school.
🇩🇪 Germany — Student Visa Rules
✅ DO: Work maximum 140 full days or 280 half days per year. This flexible annual limit (rather than a weekly cap) gives more scheduling freedom than most other countries — you can work more intensively during semester breaks and less during exams.
❌ DON'T: Exceed the annual day limit even if weekly hours look reasonable. Germany tracks total days worked per calendar year, not just hours per week — a student working steady part-time hours can still breach the limit if they don't track cumulative days.
❌ DON'T: Assume all part-time work counts the same. Working as a student assistant (Werkstudent) at your own university doesn't count against the 140/280 day limit in some cases — check with your Ausländerbehörde before assuming a role is exempt.

Frequently Asked Questions
What happens if I accidentally work one hour over the limit?
Enforcement varies by country and circumstance, but even small, unintentional breaches can trigger a compliance review. If you realize you've gone over, stop immediately, keep records, and consider consulting your institution's international student office before it's flagged externally.
Can I work full-time during officially scheduled breaks in every country?
Canada, UK, and Australia all allow full-time or unlimited work during official scheduled breaks. The US is more restrictive — F-1 students still need CPT/OPT authorization for most off-campus work even during breaks, and Germany's annual day-limit approach means breaks don't reset or exempt you from the yearly cap.
Does volunteering count toward the work hour limit?
Genuine unpaid volunteering for a registered charity generally doesn't count in most countries, but "volunteer" arrangements that involve any form of compensation (even non-cash) can be reclassified as paid work by immigration authorities — get clarity from your institution before assuming an arrangement is exempt.
❌ Violations That Apply EVERYWHERE
- Criminal convictions — even minor arrests can result in visa cancellation and deportation. No exceptions.
- Overstaying your visa — once your student visa expires, you have limited days to leave. Overstaying creates multi-year bans.
- Misrepresenting employment — lying to immigration authorities is a serious offence in every country.
- Domestic disputes that escalate to police — any police involvement can affect your immigration status, even if charges are not filed.
- Social media posts showing rule violations — immigration officers do check social media.
