An invitation letter is not required for a B-2 visitor visa application, and the State Department does not treat it as a decision factor. Many families still include one because it gives the consular officer useful context: who is inviting you, why, and for how long. This guide covers what the letter should include, the mistakes worth avoiding, and 2 ready-to-adapt sample letters.
The letter is not what decides the visa
The first thing to know in 2026: approval of a B-1/B-2 visa rests on the applicant's own situation, not on assurances from family or friends in the United States. The consular officer weighs the applicant's ties to their home country, the purpose of the trip, and their intent to return.
An invitation letter replaces none of that. Its job is more modest and still worth doing: it confirms the reason for the visit, the planned dates, and where the applicant will stay. Presenting one does not secure the visa, and leaving it out does not sink the application.
Who can write an invitation letter?
Any U.S. citizen or legal permanent resident can write one. Your host needs to be able to prove their status (a U.S. passport, a naturalization certificate, or both sides of a green card) and to have a relationship with you: family, friendship, or a relevant institution.
Writing the letter does not create a legal obligation on its own. If your host offers to cover your expenses during the stay, that is a voluntary commitment the letter can state clearly, but the letter is not a contract or a guarantee to the government.
How to write an invitation letter: what to do and what to avoid
Do:
- Write the letter in English. A letter in any other language is no use to the consular officer.
- State your immigration status (citizen or legal permanent resident) and attach the document that proves it.
- State your relationship to the applicant. If you are a relative, be ready to prove it.
- Give the reason for the visit and the planned entry and exit dates.
- Have someone else proofread the letter before you send it.
Avoid:
- Leaving out your details: full legal name, address, phone number, and email address.
- Forgetting the documents that prove your status or your relationship to the applicant.
- Submitting a handwritten letter. It should be typed.
- Sending it unsigned.
- Errors in names or contact details. Share the draft with the applicant so they can confirm everything is exact.
Common invitation letter mistakes
The most frequent mistake is leaving information out: dates, contact details, or the document proving the host's status. The second is inaccurate information, like a nickname where the full legal name on the passport belongs.
Another classic is writing the letter in the applicant's native language. The letter is addressed to a U.S. government official and needs to be in English. If the applicant speaks no English, walk them through what it says so they can answer questions about it in the interview.
Finally, resist turning it into an essay. Short sentences, concrete facts, zero flourishes. The consular officer reads hundreds of these; yours earns points by being clear, not elegant.

Frequently asked questions
Is an invitation letter required for a U.S. visitor visa?
No. The State Department does not require one, and it is not a factor in the decision. The visa is approved or refused on the applicant's own situation: their ties to their home country, the purpose of the trip, and their intent to return. The letter only adds context about the visit.
Is an invitation letter the same as a sponsorship letter?
People use the terms interchangeably, but they differ. An invitation letter confirms the visit and the host's relationship to the applicant. A formal sponsorship involves Form I-134, a separate financial commitment that is not part of a standard tourist visa application. For a B-2 visit, the invitation letter is the document this guide covers.
What can I do to improve my chances of visa approval?
Show strong ties to your home country, such as stable employment, studies, family, or property, and a clear purpose of travel. Bring evidence of your finances and answer honestly in the interview. A well-written invitation letter can accompany all of this, but it replaces none of it.
How much money do I need in the bank for a U.S. visa?
There is no official amount. What matters is showing you can cover the costs of your trip: bank statements, proof of employment, or tax returns. If your host will cover your expenses, their letter can say so explicitly.
