Frequently Asked Questions: Visa Sponsorship & Undertaking Letters

Key guidelines for family sponsors, hosts, and corporate signatories preparing a visa sponsorship packet.

What is a Visa Sponsorship & Financial Undertaking Letter?

A Visa Sponsorship Letter is a formal written declaration signed by a family member, relative, spouse, host, or employing company confirming that they will financially cover your travel, accommodation, and daily living expenses during your trip, and guaranteeing that you will comply with visa rules and return home on time.

What documents must a sponsor attach to a visa sponsorship letter?

A financial or host sponsor should attach a copy of their passport or residence permit, their last 3 to 6 months official bank statements, proof of employment/income (employment letter and payslips or tax return), proof of relationship (birth or marriage certificate for family sponsors), and proof of accommodation (tenancy agreement, title deed, utility bill, or confirmed hotel booking).

What is the difference between a Family Financial Sponsor and a Host Accommodation Sponsor?

A Family Financial Sponsor undertakes responsibility for all trip expenses (flights, daily subsistence, accommodation, and medical/repatriation costs). A Host Accommodation Sponsor specifically invites the applicant to reside at the host’s home (or a pre-booked hotel) for the duration of the trip, while the applicant may still self-fund their flights or daily spending.

Does a sponsored visa applicant still need a flight itinerary and hotel confirmation?

Yes. Embassies require a verifiable round-trip flight itinerary for every short-stay visa applicant regardless of who pays for the trip. If the applicant is not staying at the sponsor’s personal residence (or if travelling to additional cities), a confirmed hotel reservation matching the itinerary dates is also required.

How does a Corporate / Business Trip Sponsorship Letter work?

When an employer or client company sponsors a business visitor, the letter must be printed on official corporate letterhead, state the company registration number, specify the exact business meetings or conferences being attended, and guarantee 100% coverage of airfare, hotel reservations, and per diem expenses.

Does a sponsorship letter need to be notarized or attested by a municipality?

A signed sponsorship letter is accepted directly by UKVI and many consulates alongside bank statements and ID. However, certain Schengen countries also require an official municipal sponsorship form (such as Germany’s Verpflichtungserklärung, France’s Attestation d’accueil, or the Netherlands’ Bewijs van garantstelling) if the applicant does not meet personal bank balance thresholds.
