An invitation letter is the document in which a host — a resident or citizen of the destination country — confirms in writing that they are expecting a specific visitor, on specific dates, at a specific address. It is one of the supporting documents a consulate reads to decide whether a short-stay visa application is credible.
It is not a legal guarantee, it is not a visa, and on its own it does not entitle anyone to enter a country. What it does is answer three questions the visa officer is already asking: who is this person visiting, where will they sleep, and who is accountable for them while they are there.
The host writes it — not the traveller
This is the single most common mistake. The letter is written and signed by the person in the destination country, and addressed either to the consulate or to the visitor. A letter the applicant wrote about themselves carries no weight, because the whole point of the document is that a third party is vouching for the trip.
The host can be a private individual (family, friend) or a company inviting someone for business. The rules differ slightly: a business invitation is written on company letterhead and signed by someone with authority to commit the company.
What every consulate expects to find in it
Whatever the destination, the same core information turns up on every checklist. If one of these is missing, the letter is the weak document in an otherwise good file.
- The host's full identity: name, date of birth, nationality or residence status, full address, phone number and email.
- The visitor's full identity: name exactly as written in the passport, date of birth, nationality, passport number, and the relationship to the host.
- Exact dates: arrival and departure, not "about two weeks in spring". Vague dates are read as an unplanned trip.
- The purpose of the visit: tourism, family visit, wedding, conference, medical treatment. Be specific and consistent with the rest of the file.
- The accommodation address, and a sentence stating who pays for what — accommodation only, or accommodation plus living costs.
- Place, date and handwritten signature. An unsigned letter is routinely rejected.
Keep it to one page. A visa officer reads hundreds of files a week; a dense two-page letter is not more convincing, it is less.
France and the Schengen area: invitation letter or attestation d'accueil?
This trips up a lot of applicants, and the two documents are not interchangeable. For a short stay with a private host in France, the official document is the attestation d'accueil: the host requests it at their town hall (mairie), pays a stamp duty, and the mairie validates it. A letter written at home does not replace it.
We cover that procedure in detail — CERFA form, supporting documents, timeline — in our guide to the attestation d'accueil for a France visa.
An invitation letter is still useful alongside it: it explains the trip, the relationship and the itinerary in a way the standardised CERFA form cannot. And for other Schengen states — Germany, Spain, Italy, the Netherlands — a private invitation letter plus proof of accommodation is often exactly what is asked for, without any town-hall step. Always check the list published by the consulate handling your file, because it is the consulate's list that decides, not the general rule.
United Kingdom: Standard Visitor visa
The UK does not require an invitation letter, and there is no official form. But when a visitor is staying with someone rather than in a hotel, a letter from the host is the natural way to evidence accommodation. Name the host's immigration status (British citizen, settled status, valid visa) and attach a copy of the relevant page or share code, plus proof of address.
The decision hinges on whether the applicant is a genuine visitor who will leave at the end of the stay. So the letter should reinforce that: mention the return date, and that the visitor has a job, studies or family to return to.
United States: B-2 visitor visa
For a B-1/B-2 application the invitation letter is optional and never decisive — the interview is. Consular officers assess ties to the home country first. A letter from a US-based host still helps by making the itinerary concrete, and it is worth carrying to the interview rather than only uploading it.
If the host is covering costs, the letter can be accompanied by evidence of their means. Form I-134 exists for that purpose but is not required for ordinary tourism.
Documents to attach
- Copy of the host's ID, passport or residence permit.
- Proof of the host's address: recent utility bill, tenancy agreement or property deed, generally less than three months old.
- Proof of the host's means if they are covering the visitor's costs: payslips, tax notice or bank statements.
- Proof of the relationship where it is claimed: family record book, photos, message history for a long-standing friendship.
- The visitor's travel insurance and return ticket, which belong to the applicant's own file.
The mistakes that get a file refused
- Dates that contradict the flight booking or the insurance. Consulates cross-check; an inconsistency reads as an unplanned or dishonest trip.
- Promising more than you can prove. Do not write that you will cover all costs if your income cannot support it — the claim will be tested.
- A generic template left half-filled. "Dear Sir or Madam, I invite my friend" with no names, no passport number and no address is worth nothing.
- No signature, or a typed one. Sign by hand, then scan.
- Sending a letter where an attestation d'accueil is required. For France, a private host's letter alone does not satisfy the accommodation requirement.
Write it in a couple of minutes
The structure is always the same, which is exactly why it is worth generating rather than rewriting from scratch: identities, dates, address, purpose, financial commitment, signature. Our invitation letter generator asks for those fields and produces a one-page letter formatted for a consulate file, ready to print and sign.
