For most UK applicants, getting a US visa takes about two to three months from the day you start your application to the day your passport comes back with the visa inside. The single biggest variable in how long it takes to get a US visa from the UK is the wait for an interview appointment, which as of early 2026 runs about six weeks for visitor visas at the London embassy and under two weeks for students and petition-based workers.1U.S. Department of State. Global Visa Wait Times After a successful interview, add another one to two weeks for the visa to be printed and delivered.
Check Whether You Need a Visa First
British citizens with the unrestricted right of permanent abode in the UK qualify for the Visa Waiver Program and can visit the US for up to 90 days for tourism or business without a visa.2U.S. Department of State. Visa Waiver Program You register through ESTA instead, and approval usually comes within 72 hours.3USAGov. Visa Waiver Program and ESTA Application If you plan to study, work, or stay longer than 90 days, ESTA won’t cover you and the visa timeline below applies.
Where the Weeks Actually Go
The calendar time in a visa application is not spent filling out forms. It’s spent waiting for the interview slot. Everything else moves in days.
The DS-160 online application takes a few hours to a full day if you have your passport, travel details, dates of your last five US visits, and education and work history to hand.4U.S. Department of State. DS-160 Frequently Asked Questions Students add their SEVIS ID from the I-20 or DS-2019; petition-based workers add a copy of their I-129. You’ll also upload a digital photo meeting State Department specifications, and a rejected photo is one of the easiest ways to lose days on an otherwise clean application.
After the DS-160 is confirmed, you pay the Machine Readable Visa fee, which is nonrefundable. It’s $185 for most visitor and student visas, $205 for petition-based work visas (H, L, O, P, Q, R), and $315 for E-category treaty trader and investor visas.5U.S. Department of State. Fees for Visa Services Paying the fee unlocks scheduling.
F and M students have one extra step before the interview: paying the I-901 SEVIS fee and bringing proof to the consulate. If the receipt needs correcting, the processing center asks for at least two weeks’ lead time, so pay early.6Study in the States. Paying the I-901 SEVIS Fee
The Interview Wait Is the Timeline
London appointment availability shifts constantly and varies sharply by visa type. As of February 2026, the next available B1/B2 slot was about 1.5 months out, while F, M, J, H, L, O, P, and Q applicants could book in under two weeks.1U.S. Department of State.

Nearly all nonimmigrant applicants need an in-person interview. The waiver exceptions are narrow: mostly B1/B2 renewals within 12 months of expiry for adults, plus H-2A renewals within the same window and diplomatic categories.7U.S. Department of State. Interview Waiver Update First-time applicants should expect to interview.
Interview Day and What Comes Next
Time inside the embassy is short. The interview itself typically lasts one to five minutes. Leave laptops, large bags, and luggage at home, because the embassy won’t let them in. The consular officer reviews your documents, asks about your travel purpose, and usually gives an immediate verbal decision.
If you’re approved, the officer keeps your passport for printing. If you’re refused, you’ll be told why. A refusal under Section 221(g) of the Immigration and Nationality Act means either that additional documents are needed or that the case has gone into administrative processing.8U.S. Department of State. Visa Denials The first is fixable in days. The second is where timelines break down.
Administrative Processing: The Wildcard
Administrative processing is the stage that can turn a two-month application into a six-month one. The State Department describes the duration only as varying “based on individual circumstances” and offers no standard timeframe.9U.S. Department of State. Administrative Processing Information Most cases resolve in weeks to a few months. Some drag on longer. You cannot expedite it, and the State Department won’t accept status inquiries until 60 days after the interview.
Certain applicants get flagged more often. The Technology Alert List covers 16 fields, including nuclear technology, advanced computing, missile systems, chemical and biotechnology engineering, information security, and robotics. Researchers, graduate students, and workers connected to those areas should build extra months into their planning.
Getting Your Passport Back
After approval, the embassy needs three to five working days to print the visa and place it in your passport. UK delivery takes about another five working days.10U.S. Embassy and Consulates in the United Kingdom. NIV Processing Times and Return of Passport You pick your delivery option when you schedule the appointment and can track the shipment online. Plan for one to two weeks between hearing “approved” and having your passport in hand.
How Visa Category Changes the Total Time
Visa type is the strongest predictor of how long your case will take.
- B1/B2 visitor: the longest interview wait, around six weeks in London right now. Total time start to finish usually two to three months.
- F and M student: interview waits often under two weeks. Sensitive research fields should budget extra time for possible administrative processing.
- H, L, O, P, Q temporary worker: interview waits typically under two weeks, but the underlying I-129 petition must already be approved by USCIS, and that petition has its own separate timeline measured in months.
- E treaty trader or investor: higher $315 fee and heavier documentation; interview waits closer to the petition-based categories.5U.S. Department of State. Fees for Visa Services
If the consular officer finds you ineligible under immigration law and a waiver is required, expect up to nine months from the interview date at both London and Belfast.11U.S. Embassy and Consulates in the United Kingdom. Ineligibilities and Waivers
Emergency and Expedited Appointments
A genuine emergency can move your interview date forward. Qualifying situations include funerals, medical emergencies, and imminent school start dates, and you’ll need documentation. You must first submit the DS-160, pay the MRV fee, and book the earliest regular appointment before requesting expedited scheduling.12U.S. Department of State. Visa Appointment Wait Times
Weddings, graduations, conferences, assisting pregnant relatives, and last-minute tourism do not qualify. The consulate is explicit about these exclusions.
Immigrant Visas Take Longer
If you’re applying for an immigrant visa (family-based, employment-based, or diversity visa) rather than a nonimmigrant one, the timeline stretches considerably. Two extra requirements are the main reason.
You must complete a medical examination at a designated clinic at least two weeks before the interview, with results sent directly to the embassy. If the doctor orders additional tests, you can’t attend the scheduled interview and must rebook after the exam is confirmed complete.13U.S. Department of State. U.S. Embassy London Supplement
Many immigrant categories also require an ACRO police certificate. Standard processing takes up to 20 working days at £68; the premium service is £121 with up to two working days’ turnaround. ACRO warns against making travel or employment plans before the certificate arrives.14ACRO Criminal Records Office. Police Certificate
Add the medical exam, the police certificate, more extensive background checks, and the possibility of administrative processing, and immigrant visa applicants should expect several months at a minimum. If a waiver of ineligibility is required, up to nine months from the interview date.11U.S. Embassy and Consulates in the United Kingdom. Ineligibilities and Waivers
