Official Support Letter & Financial Guarantee for Schengen and Long-Stay Visas

When applying for a Swiss visa, many visitors must provide a Sponsor Letter, also called a Declaration of Guarantee (“attestation de prise en charge”). This document proves that a Swiss resident or sponsor will take financial responsibility for the applicant during their stay.

Swiss-Guarantor helps sponsors and applicants meet these requirements quickly and professionally — including providing an accepted financial guarantee when additional proof is needed.

What Is a Sponsor Letter for a Swiss Visa?

A sponsor letter is a written and signed declaration confirming that a person in Switzerland (or sometimes abroad) agrees to:

  • cover accommodation
  • pay for daily living expenses
  • provide financial support during the entire stay
  • take responsibility for potential medical or repatriation costs

This letter is commonly requested by Swiss embassies as part of Schengen Visa (Type C) or National Visa (Type D) applications.

It strengthens the visa file by ensuring the applicant has dependable financial backing.

Who Needs a Sponsor Letter?

Swiss authorities may ask for a sponsor letter when the applicant:

✔ Cannot show sufficient personal funds

✔ Is visiting family or friends

✔ Will stay with a host (non-commercial accommodation)

✔ Is a student supported by relatives

✔ Is young, retired, unemployed, or has irregular income

In many cases, a sponsor letter is accepted only if the sponsor can already prove financial capacity. This is where Swiss-Guarantor greatly helps.

What Must Be Included in the Sponsor Letter?

Swiss consulates typically require:

Sponsor’s information

  • Full name
  • Address in Switzerland
  • Residency status
  • Occupation
  • Proof of income or financial means

Applicant’s information

  • Full name
  • Relationship to the sponsor
  • Duration and purpose of stay

Financial responsibility statement

A clear written commitment to cover:

  • travel costs
  • accommodation
  • living expenses
  • emergency or repatriation costs

Swiss-Guarantor can provide a template or an enhanced financial guarantee to accompany your sponsor letter.

When Is a Financial Guarantee Required?

Even with a sponsor letter, Swiss consulates often request additional financial proof if:

  • the sponsor’s income is too low
  • the sponsor has irregular finances
  • the applicant is staying for a long period
  • the declared support is not sufficiently documented

Swiss-Guarantor offers an accepted financial guarantee that strengthens the sponsor letter and meets embassy requirements.
