What Is an Invitation Letter for a US Visa?
An invitation letter for a US visa is a personal letter you write to support someone’s application. In it, you explain why they’re visiting, how you’re connected, and what their travel plans look like.
The letter is then submitted with their visa application to the US embassy or consulate. The goal of an invitation letter for a US visitor visa is to make it clear that the visit has a specific purpose, a planned itinerary, and an end date.
When Do You Need an Invitation Letter for a US Visitor Visa Application?
An invitation letter for a US visitor visa isn’t required by the US government, but it is still recommended. It gives the embassy or consular officer a more complete view of the trip during the visa interview. Including one is a smart extra step when:
- First-time application: The visitor is applying for a US visa for the first time
- Financial support: You’re covering their travel or accommodation costs
- Stronger application: You want to make the application more complete and easier to follow
An invitation letter is useful across multiple visa types:
- B-2 tourist visa: A letter from a friend or family member about vacation plans
- B-1 business visa: A letter from a US company explaining the reason for meetings or an event
- J-1 exchange visitor visa: An optional support letter from the host organization or contact in the US
Visitors from Visa Waiver Program (VWP) countries typically don’t need a visa for trips under 90 days. But if they apply for one, an invitation letter for a US visitor visa can help tie the travel details together and show the visit has a clear purpose.
How to Write an Invitation Letter for a US Visa Application
The US hit a record 11.5 million visas in 2024. Of those, 8.5 million were visitor visas. While those numbers will likely shift, the bar remains high.
That’s why many applicants use an invitation letter to help back up their visa request. And if you’re writing one, it’s easier when you know what to include. Here’s how to do it step by step.
1. Start With a Template
A template helps you move through the process quickly and stay organized. Legal Templates’ customizable letter of invitation for a US visa walks you through each section so you know exactly what to include.
2. Add Your Information as the Host
Start by introducing yourself. This helps show who is inviting the visitor and where you’re based. Make sure to include your:
- Full name
- US address
- Phone number
- Email address
Then, state your immigration status. Clearly say if you are a US citizen or a permanent resident. End this section by adding the date you’re writing the letter.
3. Include the Visitor’s Details
Next, provide information about the person you’re inviting. This helps connect their identity to the purpose of the trip. Include their:
- Full name
- Home address
- Passport number
- Date of birth
Share how you know the visitor. Are they a friend, family member, or business contact? You can also include the location of their scheduled visa interview if you have it.
4. Describe the Visit
Explain why they’re coming to the US. This could be for tourism, a family event, business meetings, or medical treatment. List the planned arrival and departure dates. Be clear about where they’ll stay during the visit.
5. Mention Financial Support if You’re Offering It
If you’re paying for any part of the trip, such as housing, food, or travel, say so directly. You might also need to fill out Form I-134, Affidavit of Support, which confirms you agree to support the visitor during their stay. A separate form is required for each person you’re sponsoring. If the visitor is covering their own expenses, you can skip the form.
6. Sign Off the Letter
At the end of the letter, repeat your contact information so it’s easy to find. Then, sign the letter and print your name below the signature. If you think it would help, you can also include proof of income or a copy of your US ID, though that’s optional.
7. Send the Letter to the Visitor
Once the letter is complete, send it to the visitor so they can bring it to their visa interview. They should include it with their:
- DS-160 confirmation
- Passport
- Visa photos
- Proof of ties to their home country (such as a job letter, property documents, or family commitments)
Invitation Letters vs. Character References
Keep in mind that an invitation letter for a US visitor visa is not a character reference. It should focus only on the visitor’s travel plans, your relationship, and trip-related details.
