UK Student Visa Application for International Boarding School Students: What Families Handle Directly

Last Updated: May 2026

The UK Student Visa for students under 18 at boarding schools requires several steps that families complete independently, separate from what the school handles administratively. The school issues the CAS (Confirmation of Acceptance for Studies) number - the formal visa sponsorship document - but document preparation, financial evidence, guardian arrangements, and the visa application itself are family-led responsibilities. According to IIE Open Doors (2024), demand for UK-based high school placements among international families has grown alongside US pathway programs, making UK student visa literacy increasingly important for parents beginning the enrollment process.

Amerigo Education partners with 40 Niche A+/A rated schools (independent academic rankings based on school-reported curriculum quality, faculty credentials, student outcomes, and college matriculation data) across the US, Canada, and the UK, supporting 3,500+ students from 55+ countries. The Class of 2025 achieved 97% admission to Top 100 US universities. Amerigo's UK partner schools are Brentwood School in Essex and Berkhamsted School - both of which handle their own admissions, CAS issuance, and university counseling through each school's own teams, with Amerigo providing enrollment coordination and administrative support.

This guide covers what the UK Student Visa requires, which documents families prepare independently, how the application is submitted, what role the school plays versus what families handle directly, and what Amerigo's administrative support includes for UK-bound students.

Key Takeaways

• CAS from the school: The boarding school issues the CAS number after enrollment is confirmed - families cannot apply for the UK Student Visa without it.
• Family-led documents: Financial evidence, passport, TB test (where nationality-specific), and guardian arrangement are all prepared by families independently.
• UK guardian requirement: Students under 18 boarding in the UK require an approved UK-based guardian - a regulatory requirement families arrange and pay for separately from Amerigo.
• UKVI application: Families submit the visa application through the UK Visas and Immigration (UKVI) online portal and attend a biometric appointment at a Visa Application Centre in their home country.
• Amerigo's UK role: Amerigo provides enrollment coordination and administrative support at Brentwood and Berkhamsted - the UK Student Visa is handled directly by the family with the school's admissions team.

What Is the UK Student Visa for Boarding Schools?

The UK Student Visa (formerly the Tier 4 Child visa) is the visa category for international students aged 4-17 enrolling at DfE (Department for Education) registered schools in the UK. For students at independent boarding schools, the Student Visa covers the duration of the boarding program.

The visa allows:

1. Enrollment at the sponsoring school: The student is linked to the school named in the CAS - changing schools during the visa period requires notifying UKVI.
2. Residence during term and holidays: Unlike some visa categories, boarding school students on the UK Student Visa may remain in the UK during school vacations if they are boarding students.
3. Leave and re-entry: Students can travel outside the UK during holidays and re-enter on the same visa for the duration of the approval period.

What Documents Do Families Prepare for the Visa?

Most UK Student Visa documentation is prepared by families independently of the school's administrative process. According to NAIS (2024), international families enrolling at private boarding schools consistently identify visa document preparation as among the most complex stages of the enrollment process.

Key documents families prepare:

1. Valid passport: Must have sufficient validity to cover the visa period - typically at least 6 months beyond the program end date.
2. Financial evidence: Bank statements from the past 28 days showing funds to cover tuition and living costs for the program duration.
3. Tuberculosis (TB) test certificate: Required for applicants from certain countries, completed at a UKVI-approved clinic before application submission.
4. Guardianship arrangement: Students under 18 must name a UK-based guardian approved by the school - families select and pay a guardianship service independently.

Families should confirm the full document list with the school's admissions team early in the enrollment process, as requirements vary by nationality and program length.

How Is the Visa Application Submitted?

The UK Student Visa application is submitted online through the UKVI portal. Families complete the online form, upload required documents, and pay the visa application fee plus the Immigration Health Surcharge (IHS) - which covers NHS healthcare access during the stay.

The application process:

1. Receive the CAS from the school: The school provides the CAS reference number once enrollment is confirmed and required deposits or fees are received.
2. Complete the UKVI online application: Enter the CAS reference number and personal details on the official UKVI portal.
3. Pay the visa fee and IHS: The visa application fee (for students under 18) and the Immigration Health Surcharge are paid online at submission.
4. Book a biometric appointment: After submission, families book an appointment at a Visa Application Centre (VAC) in their home country to provide fingerprints and a photograph.

Families should submit the visa application no earlier than 3 months before the intended travel date. Most decisions are issued within 3 weeks from the biometric appointment, though processing times vary by country and application volume.

What Happens at the Visa Application Centre?

The VAC (Visa Application Centre) appointment collects biometric data - fingerprints and a photograph - for the UKVI decision-making process. The VAC does not assess the application itself; it forwards the biometric data to the UKVI review team.

At the VAC appointment:

1. Present the booking confirmation: Confirm the scheduled appointment with the reference number from the booking email.
2. Submit original documents: The VAC may request original copies of the passport, financial statements, and TB certificate - families should bring originals, not only digital versions.
3. Provide biometric data: Fingerprints and photograph are collected electronically.
4. Await the UKVI decision: The UKVI team reviews the full application after the VAC and issues a decision by email within the standard processing window.

According to NACAC (2024), early document preparation is one of the most effective ways international families reduce visa-related delays in international enrollment timelines.

What Do Schools Handle in the UK Visa Process?

The school's role is to issue the CAS and confirm the student's enrollment status to UKVI as a licensed sponsor. The school is responsible for the accuracy of the CAS data it submits to the visa system.

Schools also typically:

1. Confirm enrollment and payments: The CAS is issued only after the school confirms the student's place and receives required deposits or fees.
2. Provide a formal acceptance letter: Some UKVI applications include a school acceptance letter alongside the CAS as supporting documentation.
3. Specify guardian approval requirements: Boarding schools define which guardianship providers are accepted - families must select a guardian from the school's approved provider list.
4. Issue the Biometric Residence Permit (BRP): After arrival in the UK, the school often serves as the collection point for the BRP card, which the student must collect within 10 days of arrival.

Brentwood School and Berkhamsted School manage their own CAS issuance through their respective international admissions teams.

How Does Amerigo Support UK Visa Preparation?

Amerigo's role at Brentwood School in Essex and Berkhamsted School covers enrollment coordination, administrative support, and native-language family communication - not visa processing or university counseling. Families handle the UK Student Visa application directly with each school's admissions team.

Amerigo's in-country staff communicate with Chinese families via WeChat and with families from Korea, Vietnam, Mexico, and the Taiwan Region in their native language throughout the pre-departure period. General enrollment and timeline questions are answered by Amerigo's in-country enrollment team - but the UKVI application is submitted by the family directly through the official portal.

Amerigo does not provide or charge for UK guardianship. UK guardianship fees are not charged by Amerigo and are not included in tuition - families arrange and pay guardianship separately as a UK regulatory requirement. Families can download the Amerigo brochure for a full overview of UK program costs and enrollment steps.

Frequently Asked Questions

What is the UK Student Visa for students under 18?

The UK Student Visa is the visa category for international students aged 4-17 attending DfE-registered schools in the UK, including independent boarding schools. Students at boarding programs must hold a valid UK Student Visa for the full duration of their enrollment. The visa is tied to the sponsoring school through the CAS (Confirmation of Acceptance for Studies) system and managed by UK Visas and Immigration.

What is a CAS number and who provides it?

The CAS (Confirmation of Acceptance for Studies) is a unique reference number issued by the school to each accepted international student. It confirms enrollment and the school's agreement to sponsor the visa application. Families cannot submit the UK Student Visa application without the CAS number. The school's admissions team issues the CAS after enrollment is confirmed and required payments are received.

What financial evidence is required for the UK Student Visa?

Families must show sufficient funds to cover school fees for the course and monthly living costs for the UK portion of the stay. Bank statements from the past 28 days are typically required. The specific amount varies based on school fees and program duration - families should request the current UKVI financial requirements from the school's admissions team before preparing documents.

Does my child need a UK guardian for the Student Visa?

Yes - students under 18 attending boarding school in the UK are required by most schools to name an approved UK-based guardian as a condition of enrollment. UK guardianship fees are not charged by Amerigo and are not included in tuition - families arrange and pay guardianship independently as a UK regulatory and school requirement. The guardian must be selected from the school's approved provider list.

How long does the UK Student Visa application take?

UK Student Visa decisions are typically issued within 3 weeks from the biometric appointment at the Visa Application Centre. Processing times vary by country and application volume at VAC locations. Families should submit the application no earlier than 3 months before travel and allow time for biometric appointment booking, document collection, and the decision period before the school term start date.

What English tests are accepted for the UK Student Visa?

The UK Student Visa for students under 18 at boarding schools does not typically require a separate English proficiency test as part of the visa application - the school assesses English proficiency through its own admissions process. Families should confirm specific English requirements with the school's admissions team, as individual school policies may differ from standard UKVI guidance for adult student visas.

How much does the UK Student Visa cost in 2026?

The UK Student Visa application fee for students under 18 is set by the Home Office and can change annually. The Immigration Health Surcharge (IHS) is an additional upfront cost for the visa duration and covers NHS healthcare access during the stay. Families should check the current fee schedule on the UK government's official UKVI website before budgeting, as fees are updated periodically.

Can Amerigo families apply to Brentwood through the UK Student Visa route?

Yes - Brentwood School in Essex and Berkhamsted School, Amerigo's UK partner schools, both accept international students on the UK Student Visa route. Each school manages its own admissions and CAS issuance. Amerigo provides enrollment coordination and administrative support throughout the application process. Families applying to Brentwood or Berkhamsted should contact Amerigo's enrollment team directly to begin the process.

What happens if the UK Student Visa application is refused?

If the visa application is refused, the refusal letter states the reason. Common causes include insufficient financial evidence, incomplete documentation, or issues with the CAS. Families can reapply after addressing the reason for refusal. The school's admissions team and Amerigo's enrollment coordination team can advise on next steps - but the reapplication is submitted by the family directly through UKVI.

What is the role of a guardianship service for UK boarding students?

A UK guardianship service acts as a local contact for the student and family while the student is in the UK. The guardian is an approved adult who can act in the family's interests in emergencies and provide support during school holidays when students cannot travel home. Boarding schools specify which guardianship providers they accept - families select a service from the school's approved list and pay the guardianship fee directly to the provider.

Conclusion

The UK Student Visa for boarding school students is a family-led process supported by the school's CAS issuance and admissions team. Financial evidence, guardianship arrangements, and biometric appointments are all managed by families directly through the UKVI portal.
