Choosing between a UK Student visa and a US F-1 visa is really two different decisions wearing one question: how much certainty do you want in the visa process itself, and how long do you want to work in-country afterward? Both are legitimate, well-trodden routes, but they differ enough on cost, risk, and post-study rights that the “right” answer depends heavily on your field of study, budget, and nationality. This guide lays out the concrete numbers side by side. None of this is legal advice — treat it as a starting framework, then confirm the exact figures that apply to you on gov.uk or travel.state.gov before you apply.
The core structural difference
The UK Student visa is built around a single document: your CAS (Confirmation of Acceptance for Studies), issued by a Home Office-licensed sponsor once you’ve accepted an offer. Submit your CAS, finances, and biometrics, and a caseworker decides on paper — no interview in most cases.
The US F-1 process centers on your I-20, issued by your school once you’re accepted, but that’s only the start. You still have to pay the SEVIS fee, complete the DS-160, and — critically — attend an in-person interview at a US embassy or consulate where a consular officer decides, largely on the spot, whether you’ve shown enough ties to your home country to qualify under immigration law. That interview is the single biggest source of uncertainty in the entire US process.
Cost comparison
UK Student visa:
- Visa application fee: £558 (outside or inside the UK), per gov.uk
- Immigration Health Surcharge (IHS): £776 per year of your visa, paid upfront in full — a 3-year course means roughly £2,328 just for the IHS, per gov.uk’s healthcare surcharge page
- Maintenance (proof of funds): a monthly living-cost amount for up to 9 months, with a higher rate for London than elsewhere in the UK — see our proof-of-funds guide and confirm the exact current figure on gov.uk, since it is reviewed periodically
US F-1 visa:
- SEVIS I-901 fee: $350, confirmed on ICE’s SEVIS fee page
- MRV (visa application) fee: roughly $185 — confirm the exact current amount on travel.state.gov, since State Department fees are periodically adjusted
- Proof of financial support: no fixed government minimum — each school sets its own required amount based on tuition and living costs, documented on your I-20
Bottom line: the F-1’s government fees are lower upfront, but the UK’s IHS is really prepaid healthcare, not a pure visa tax — you get NHS access as a tradeoff. Tuition and cost of living generally dwarf either visa fee over a full program.
Timeline
- UK: Standard decisions take about 3 weeks from outside the UK and about 8 weeks for switching or extending from inside the UK, with a paid priority service often available, per gov.uk.
- US: There’s no single fixed processing time — it depends on interview wait times at your specific embassy or consulate, which can range from days to several months depending on location and season. Book your interview slot as early as your I-20 allows.
Work rights during study
- UK: Degree-level Student visa holders can generally work up to 20 hours a week during term-time and full-time during vacations, with some course levels and a short list of jobs excluded. Check the condition printed on your visa/BRP, since it’s binding.
- US: F-1 students generally cannot work off-campus in their first academic year. On-campus work is allowed subject to conditions. After the first year, CPT (tied to a required curricular component) and OPT (practical training in your field) open up off-campus options — see our OPT vs CPT guide for the mechanics, since misusing either can jeopardize your status.
Post-study work: Graduate visa vs OPT
This is where the two systems diverge most sharply.
- UK Graduate visa: Most bachelor’s and master’s graduates get 2 years of unrestricted work (falling to 18 months for applications made on or after 1 January 2027), and PhD graduates get 3 years — no sponsoring employer required, no job-field restriction. The fee is £937 plus the IHS (about £1,035/year per gov.uk’s figures). See our Graduate visa guide for eligibility details.
- US OPT: Standard OPT gives 12 months of work authorization tied to your field of study. STEM graduates working for an E-Verify-registered employer can extend this by 24 months, for 36 months total — longer than the UK route, but only for STEM fields, and your job must relate to your degree throughout.
If you’re in a non-STEM field, the UK’s unrestricted 2-year Graduate visa is substantially more generous than the US’s 12-month OPT. If you’re in a STEM field and want the longest possible post-study runway, OPT-plus-STEM-extension wins on raw duration — provided you land a qualifying employer.
Refusal risk and approval odds
This is the UK’s biggest structural advantage: there is no discretionary interview. Decisions are made against documented criteria (CAS, funds, English language), so a complete, honest application from a qualified applicant is rarely refused outright.
The US F-1 is different. Every applicant is legally presumed to be an intending immigrant until they prove otherwise under section 214(b) — a subjective judgment made in a short interview. Reported F-1 refusal rates have run well into the double digits in recent fiscal years and vary significantly by country of origin, and a 214(b) refusal can’t be appealed (though you can reapply). If your country has a track record of higher F-1 refusal rates, or your personal circumstances (strong ties abroad, funding source, choice of major) are easy to question, that risk should weigh heavily in your decision.
Which fits which student profile
- Pick the UK if: you want a predictable, document-based approval process; your field isn’t STEM and you want solid post-study work time regardless; you’re comfortable with the higher upfront IHS cost in exchange for NHS access and no interview risk.
- Pick the US if: you’re in a STEM field and want the longest possible post-study work window (up to 36 months); you’re confident about clearing the consular interview; your target program or research opportunity is genuinely US-specific.
- Either way: get your paperwork — financial evidence, acceptance letter/I-20, and supporting documents — airtight before you apply or interview. That’s where most avoidable refusals and delays come from, on both sides.
FAQ
Is it easier to get a UK Student visa or a US F-1 visa? The UK Student visa has a more predictable, document-based approval process once you hold a CAS from a licensed sponsor, while the F-1 relies on an in-person consular interview where the officer must be convinced you intend to return home after your studies. F-1 refusal rates under section 214(b) have run well into the double digits in recent years, and vary sharply by country, so the US path carries more subjective risk even with a strong application.
Which is cheaper, the UK Student visa or the US F-1 visa? The US F-1 visa itself is cheaper upfront, with a SEVIS I-901 fee of $350 plus a roughly $185 MRV application fee. The UK Student visa costs more at the application stage because it bundles a £558 visa fee with the mandatory Immigration Health Surcharge of £776 per year of your course, paid in full before you travel. Over a full degree, total cost depends more on tuition and living costs than on the visa fee itself.
Can I work while studying on a UK Student visa or a US F-1 visa? Yes on both, but the rules differ. UK Student visa holders on a degree-level course can generally work up to 20 hours a week during term-time and full-time during vacations. F-1 students can only work on-campus during their first academic year, after which CPT and OPT open up off-campus work tied to their field of study.
Which visa gives better post-study work options, the UK Graduate visa or US OPT? The UK Graduate visa gives most graduates 2 years of unrestricted work (18 months for applications from 1 January 2027, 3 years for PhD holders) with no employer sponsorship needed. The US gives 12 months of OPT, extendable to 36 months total for STEM graduates working for an E-Verify employer — longer for STEM fields, but it requires your job to relate to your degree and an employer willing to navigate the paperwork.
