- Most UK visa applicants outside the UK must attend a Visa Application Centre (VAC) to give biometrics: fingerprints and a digital photograph.
- Bring your appointment confirmation, valid passport, and any documents specified in your application confirmation.
- The biometric process itself takes around 10 to 15 minutes once you are seen.
- Missing an appointment without rescheduling can delay your application significantly or result in refusal.
- Children under 5 are exempt from giving fingerprints but still attend the appointment for the photograph.

A biometric appointment is a mandatory step in the UK visa application process for the majority of applicants applying from outside the United Kingdom. At the appointment, a Visa Application Centre (VAC) collects the applicant's fingerprints from all ten fingers and takes a digital facial photograph. This biometric data is linked to the visa application and stored on the UK's immigration database.
What Is a Biometric Appointment
Biometrics are required because they allow UK border staff to verify identity at the point of entry and flag any discrepancies between the person presenting themselves and the data held on file. They also form part of the UK's wider immigration enforcement infrastructure. For applicants already inside the UK making an in-country application through UKVCAS (UK Visa and Citizenship Application Services), the process is similar but uses different service points rather than overseas VACs.
Who Needs to Give Biometrics
The following categories of applicant are required to give biometrics: all applicants aged 5 and over applying for entry clearance, applicants in the UK applying to extend, switch, or settle their visa via UKVCAS, and applicants applying for a Biometric Residence Permit. Exemptions and special cases: children under 5 do not need to give fingerprints but must still attend the appointment for the photograph; applicants who have given biometrics for a previous UK visa within the last 10 years may not need to re-enrol depending on the visa route and the VAC in question; diplomatic passport holders may be exempt in some countries under bilateral agreements.
How to Book the Appointment
Biometric appointments are booked through the online visa application process on GOV.UK. Once the application form is completed and the visa fee paid, the system automatically prompts the applicant to book a VAC appointment in their country of residence. Appointments are typically available within a few days to a few weeks depending on location and time of year. Peak periods see significantly longer waits. Priority and super priority appointments may be available at an additional cost. Applicants should not travel to the VAC without a confirmed appointment; walk-ins are not accepted.
What to Bring to the Appointment
Essential items: appointment confirmation (printed or digital email showing reference number, date, time and address); valid passport (same passport used in the visa application); previous passports where required; application decision letter or application reference number. Documents to submit at the VAC if applicable: depending on the visa route and country, the VAC may also collect supporting documents on behalf of UKVI; the appointment confirmation will specify whether documents must be brought on the day.
For children: the child's appointment confirmation; the child's passport or travel document; proof of parental responsibility if the accompanying adult is not the child's parent or legal guardian.
What Happens on the Day
Arriving at the appointment with time to spare is strongly recommended. Most VACs enforce a strict late policy; arriving more than 15 to 30 minutes late can result in the appointment being forfeited. The process typically follows: check-in and document verification at the reception desk; document scanning where applicable; biometric enrolment (a VAC operator takes fingerprints from all ten fingers using a digital scanner, the process takes around 3 to 5 minutes, and a digital photograph is taken in the same session); receipt and confirmation. The entire appointment including waiting time typically takes between 30 minutes and two hours depending on the VAC and footfall on the day.
Photo Requirements at the Appointment
The digital photograph taken at the VAC replaces the need for a separate biometric photograph in most cases. However, some VACs and visa routes still require the applicant to bring two printed photographs. Where printed photographs are required, the UK visa photo specification applies: 45mm x 35mm; colour on white or cream plain background; taken within the last six months; neutral expression with mouth closed; eyes open and clearly visible (no tinted glasses, no hair covering the face); full face visible from crown to chin; no headgear unless worn for religious reasons; printed on high-quality photographic paper.
ID Checks and What Caseworkers Verify
At the biometric enrolment stage, VAC staff carry out identity checks that feed into the caseworker's assessment. The checks include matching the passport photograph to the person presenting, verifying the passport is genuine using document authentication tools, confirming the appointment and application reference numbers match, and checking that the person attending is the named applicant. Applications cannot be submitted on someone else's behalf by a third party attending the appointment in their place. More detailed identity verification, including cross-referencing biometric data against existing immigration records, occurs within UKVI systems after the appointment rather than at the VAC itself.
What Happens If You Miss the Appointment
Missing a biometric appointment without rescheduling has serious consequences. The application does not automatically cancel, but it cannot proceed to decision without biometric data. If the deadline for the application expires (typically 90 days from payment), the application will lapse and fees are not refunded. Rescheduling is possible in most cases through the VAC's online booking system, subject to availability. A rescheduling fee may apply depending on the VAC operator and country. If an appointment is missed due to circumstances outside the applicant's control, the applicant should contact the VAC operator as soon as possible with supporting documentation.
Biometrics for In-Country Applicants (UKVCAS)
Applicants already in the UK making an in-country application submit biometrics through UKVCAS rather than a VAC. UKVCAS has service points across the UK and offers three appointment tiers: Core service (free appointment at a UKVCAS Core service point, limited locations and availability); Enhanced service (fee-paying appointment at a wider range of locations and times); Premium lounge (premium fee for a private appointment in a premium facility). For in-country applicants, document upload is typically done online through the Sopra Steria portal before the biometric appointment.
Frequently Asked Questions
Do I need to bring original documents to a biometric appointment?
It depends on the VAC and visa route. Some VACs collect original supporting documents on the day; others require online upload only. Check your appointment confirmation carefully; it will specify what to bring.
How long does the appointment take?
The biometric capture itself takes around 10 to 15 minutes. Total time at the VAC including check-in and waiting is typically 30 minutes to two hours depending on how busy the centre is.
Can someone else attend the appointment on my behalf?
No. The applicant must attend in person. The biometric data must be captured from the applicant directly and VAC staff verify identity against the passport on the day.
What happens if my fingerprints cannot be taken?
If fingerprints cannot be captured due to a temporary condition such as cuts or severe dryness, the appointment may be rescheduled. In rare cases where fingerprints cannot be taken permanently, the VAC operator will advise on the alternative process.
Are children exempt from biometrics?
Children under 5 are exempt from fingerprinting but still attend the appointment for the digital photograph. Children aged 5 and over give both fingerprints and a photograph.
