What is an invitation letter and when do I need one?
An invitation letter is a signed letter from your host confirming who you are visiting and where you will stay. You mainly need one when you are not booking a hotel.

What an invitation letter is
An invitation letter is a written statement from someone in the country you are visiting, saying that they know you, that they expect you, and that you have somewhere to stay. It answers the same questions a hotel booking answers, just with a person standing behind it instead of a property.
It is not a legal invitation to enter the country and it does not guarantee you a visa. It is one supporting document among several, and a consulate still weighs it against your funds, your ties at home and your travel history.
When you actually need one
Staying with friends or family
This is the common case. You have no booking to submit, so your host writes the letter and attaches proof of their own address and status in the country.
Business trips
A business visa application usually needs a letter on the host company's letterhead naming the purpose of the visit, the dates, and who covers your costs. Your own employer often writes a matching letter confirming your role and that you are returning to work.
Staying in a hotel
You normally need no invitation letter at all. A confirmed booking made on trip1 already shows the property, the full address and your dates, which is what proof of accommodation means in practice.
What the letter has to contain
A vague letter is worse than no letter, because it invites follow-up questions. Ask your host to include all of this.
- The host's full name, home address, phone number and email
- The host's status in the country, such as citizen or resident, with a document number
- Your full name as printed in your passport, plus passport number, nationality and date of birth
- How you know each other, and the purpose of the visit
- Exact arrival and departure dates, matching the ones on your application
- Where you will sleep, and who pays for accommodation and living costs
- The host's signature and the date the letter was written
Most consulates also want copies of the host's ID or residence permit, and often proof that they live at the address, such as a utility bill or tenancy agreement.
Countries that use an official form instead
Some countries will not accept a letter your host typed at home. In Germany, a host who will cover your costs makes a formal declaration of commitment, the Verpflichtungserklärung, at their local foreigners authority after proving they can support you financially.
The Netherlands uses an official sponsorship and private accommodation form that the host signs at their municipality. Both take time and sometimes a fee, so ask your host to start early rather than a week before your appointment.
Requirements differ by destination and by your nationality, so check the consulate page for the country you are applying to before anyone signs anything. Never invent a format based on a template you found online.
Trips that mix hotels and private stays
Cover every night with something. Use booking confirmations for the hotel nights and the host's letter for the private nights, and make sure the dates join up without a gap.
Important: Never ask a host to sign a letter describing a stay that is not going to happen. Consulates call hosts to verify these letters, and a refusal recorded for a false document stays on your record and damages future applications.
Invitation letters - FAQ
No. The US State Department says a letter of invitation or affidavit of support is not needed to apply for a visitor visa, and it is not a factor in the decision. The consular officer looks at your own circumstances, such as your ties at home and the purpose of your trip, so focus on those documents instead.
GOV.UK sets no fixed format. Your host should give their name, address and contact details, their status in the UK, how they know you, your dates and where you will stay. If they are paying for your trip, the UK also asks for evidence of their funds, how they will support you and your relationship.
It is a signed letter from a host in the country you are visiting confirming who you are visiting, where you will stay, for how long and who pays. It is one supporting document among several: it does not guarantee a visa, and the consulate still weighs it against your funds, your ties at home and your travel history.
The host's full name, address, contact details and status in the country, your name, passport number and date of birth, how you know each other, exact dates, where you will sleep, who pays, and a signature and date. Some countries use an official form instead, such as Germany's Verpflichtungserklärung when the host covers your costs, or the Netherlands' sponsorship and accommodation form.
It is a letter on the host company's letterhead naming the purpose of your visit, your dates and who covers your costs. Your own employer often writes a matching letter confirming your role and that you will return to work. Check the consulate's document list, since business visa requirements differ by country and by your nationality.
Usually not. A confirmed hotel booking already shows the property, its full address and your dates, which is what proof of accommodation means. A booking made on trip1 covers that on its own. If your trip mixes hotel nights and nights with friends, use booking confirmations for the hotel nights and your host's letter for the rest.
