In short
- A Student visa for a course of 12 months or longer covers the course plus 1 month before it starts and 4 months after it ends.
- PhD graduates get 3 years on the Graduate route. Everyone else gets 2 years, dropping to 18 months for applications made on or after 1 January 2027.
- An Academic Technology Approval Scheme certificate is needed for sensitive subjects, and takes at least 30 working days.
- PhD students can bring dependants: a doctorate meets the postgraduate research course rule.
- The published 5-year cap on study is for study at degree level; there is no equivalent cap stated for study above degree level.
PhD students benefit from longer visa durations, the 3-year Graduate route, and the ability to bring dependants. But there are additional requirements like ATAS certificates for certain subjects. This guide explains everything PhD students need to know about their Student visa.
Visa Duration for PhD Students
Your Student visa for a PhD covers the course as stated on your Confirmation of Acceptance for Studies, plus fixed periods at each end. Most UK PhDs are 3 to 4 years full-time. The Immigration Rules set the extra periods by course length:
- A course of 12 months or longer (which a PhD is): 1 month before the course start date, 4 months after the course end date
- A course of 6 months or longer but under 12 months: 1 month before, 2 months after
- A pre-sessional course of less than 6 months: 1 month before, 1 month after
- Any other course of less than 6 months: 7 days before, 7 days after
The period before the course only applies where entry clearance is granted a month or more before the course starts. If it is granted less than a month before, permission starts 7 days before your intended travel date, and if it is granted less than 7 days before travel, it starts immediately.
If your PhD takes longer than expected, you can apply for a Student visa extension. On study time limits, the published caps are 2 years of permission for study below degree level and 5 years for study at degree level, counted from the age of 18. The 5-year cap does not apply to architecture, medicine, dentistry, veterinary medicine and science, music at a Conservatoires UK member college, or certain law conversion courses. The Immigration Rules do not set an equivalent cap for study above degree level.
ATAS Requirements
The Academic Technology Approval Scheme applies to taught courses and research at master's or PhD level in sensitive subjects. Whether it applies to you is decided by the subject code (called a CAH3 code) for your course or research area, which your education provider will confirm — usually on your offer letter. That is more reliable than guessing from the subject name.
GOV.UK says you do not need a certificate if you hold indefinite leave to remain, if you are exempt from UK immigration control, or if it is not a condition of your particular visa. Postgraduate diplomas and PGCEs are also outside the scheme. There is also a nationality exemption. GOV.UK lists Australia, Austria, Belgium, Bulgaria, Canada, Croatia, the Republic of Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, the Netherlands, New Zealand, Norway, Poland, Portugal, the Republic of Korea (South Korea), Romania, Singapore, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United States of America.
Apply through the ATAS guidance on GOV.UK. GOV.UK says applications take at least 30 working days (6 weeks) to process, that complex ones can take longer, that more people apply between April and August so waits are longer then, and that there is no fast-track service.
A new certificate is needed if the content of your course changes, if your primary supervisor changes, or if your course end date is delayed by 3 months or more. If your visa expires before you have written your thesis, GOV.UK says you must reapply for a certificate as well as renewing your visa.
Financial Requirements
PhD students must meet the same financial requirements as other Student visa applicants: outstanding tuition fees for one academic year, plus £1,529 a month in London or £1,171 a month outside London, for up to 9 months. That is £13,761 and £10,539. The money must be held for at least 28 days in a row, and the end of that 28-day period must be within 31 days of the date you apply.
You do not have to show funds at all if you are applying from inside the UK and have been living here with permission for 12 months or more on the date of application.
Many PhD students are funded by scholarships, research councils, or their university. If course fees have been paid, that must be confirmed on your Confirmation of Acceptance for Studies or by a receipt from your sponsor, and it reduces the amount you need to show. If you are relying on a student loan or official financial sponsorship, you need evidence of it from the loan or sponsorship body, and the 28-day rule does not apply to those funds.
Dependants
A PhD is one of the few courses that still carries the right to bring dependants. The rule is a full-time postgraduate course of 9 months or longer at a higher education provider with a track record of compliance, and for courses starting on or after 1 January 2024, the provider must confirm it is a PhD or other doctorate, or a research-based higher degree. A dependant is a spouse, civil partner, unmarried partner in a relationship similar to marriage for at least 2 years, or a child under 18.
Dependants can work with no limit on hours, but not as a professional sportsperson or sports coach, and they have no access to public funds. Each dependant must show £845 a month in London or £680 a month outside London, for up to 9 months — £7,605 and £6,120 — on top of the money you show for yourself. Each also pays a £558 application fee and the £776 a year healthcare surcharge. The dependants guide explains the costs and requirements in detail.
Work Rights During Your PhD
PhD students follow the same work rules as other Student visa holders on a full-time course at degree level or above with a higher education provider that has a track record of compliance: up to 20 hours a week during term time and full-time during vacations. Teaching and demonstrating within your university counts towards those hours, and so does voluntary work. Home Office guidance treats any period of permission after you have completed the course as outside term time.
Self-employment and business activity are not allowed. The one exception, added on 25 November 2025, is a Student with a pending Innovator Founder application supported by an endorsement from an endorsing body.
After Your PhD: The 3-Year Graduate Route
PhD graduates qualify for the Graduate route for 3 years, with no sponsor needed. Everyone else gets 2 years if they apply on or before 31 December 2026, and 18 months if they apply on or after 1 January 2027. The 3 years after a doctorate is not affected by that change.
The fee is £937, and the healthcare surcharge on the Graduate route is the standard £1,035 a year, not the £776 student rate. GOV.UK gives the 3-year surcharge as £3,105, so the total is about £4,042.
The other published routes from a PhD are the Skilled Worker visa, which needs a job offer from a licensed sponsor, and the Global Talent visa, which needs an endorsement or a qualifying prestigious prize.
Next Steps
Your education provider confirms whether an Academic Technology Approval Scheme certificate is needed for your subject code, and GOV.UK puts the processing time at least 30 working days with no fast-track option. From outside the UK, the earliest you can apply for the visa itself is 6 months before the course starts, and a decision usually takes 3 weeks. From inside the UK it is 3 months before, with a decision usually within 8 weeks.

Questions and answers
How long is a Student visa for a PhD?
A Student visa covers the course as stated on your Confirmation of Acceptance for Studies, plus a fixed period at each end. For a course of 12 months or longer, the Immigration Rules add 1 month before the course start date and 4 months after the course end date. Most UK PhDs take 3 to 4 years full-time.
Do PhD students get the 3-year Graduate route?
Yes. Someone who has completed a PhD or other doctoral qualification is granted 3 years on the Graduate route. Everyone else gets 2 years if they apply on or before 31 December 2026, and 18 months if they apply on or after 1 January 2027. The 3 years for a doctorate is unchanged by that.
Do I need an ATAS certificate for my PhD?
You need an Academic Technology Approval Scheme certificate if your research is in a sensitive subject at master's or PhD level. Your education provider confirms whether it applies to your subject code. GOV.UK says applications take at least 30 working days (6 weeks) to process, that complex ones can take longer, and that there is no fast-track service. Nationals of a published list of countries, and people with indefinite leave to remain, do not need one.
Can PhD students bring dependants?
Yes. A PhD is a doctorate, so it meets the rule that a postgraduate course starting on or after 1 January 2024 must be a PhD, other doctorate, or research-based higher degree. The course must be full-time, 9 months or longer, and with a higher education provider that has a track record of compliance. Dependants can work with no limit on hours, but not as a professional sportsperson.
