What's Inside

Many U.S. citizens and legal permanent residents have friends and family living abroad whom they may want to invite to the United States for a temporary visit. When this happens, people often forget that there are certain requirements a foreign national must meet to obtain a travel visa and gain lawful entry into the country. 

While not a requirement, a letter of invitation can be used as supporting documentation for a loved one’s B-1 or B-2 visa application to help them meet their application requirements. 

If you’ve been asked to prepare an invitation letter for a U.S. visa application and aren’t sure where to begin, this guide may help. We discuss what a letter of invitation is, describe how to prepare one and provide an invitation letter for visa example that you can use as you craft your own.

Invitation letter for U.S. visa application defined

An invitation letter is a document written by an individual formally inviting a family member or friend who’s a foreign national to the U.S. for a specific period of time. Invitation letters are often used as supporting documentation to the foreign national’s visa application when seeking temporary entry into the U.S.

The purpose of an invitation letter is to confirm the details of the applicant’s stay, including the reason for and dates of their travel. While an invitation letter isn’t a specific requirement for any visa application, including one with the application or bringing one to the visa application interview may be beneficial.

When to submit a letter of invitation

If a friend or relative plans to visit you on a temporary travel visa, they may ask you to provide them a letter of invitation to submit in support of their visa application. Below are two common visitor visas for which you may consider submitting an invitation letter:

– Settle an estateNegotiate a contract
B-2Tourism– Tourism
– Vacation

Regardless of the precise scenario, if a friend, family member or colleague requests an invitation letter, providing one may help enhance their chances of a successful application.

The timing of the letter’s submission doesn’t matter since a letter of invitation isn’t required when filing the initial application for a visitor visa. You may include a letter of invitation as additional documentation in support of your application, or you may also choose to bring one with you to your interview.

Who can write an invitation letter for U.S. visa applications

An invitation letter should be written by the individual who will host the foreign national during their stay in the U.S. and who has personal ties to the invitee. 

Typically, the individual writing the invitation letter is either a U.S. citizen or lawful permanent resident (LPR). In many cases, the host is a friend or family member of the visa applicant. However, colleagues and business associates may also write letters.

How to write a letter of invitation for U.S. visa applications

Because providing an invitation letter is optional, there’s no specific list of information that one must contain. Nevertheless, below are some examples of information that’s often included: 

  • The host’s name and contact information
  • The host’s citizenship or immigration status
  • The visa applicant’s name and contact information
  • Details regarding the relationship between the host and the visa applicant
  • Name and contact information for the visa applicant’s foreign employer
  • The visa applicant’s expected travel dates
  • Details regarding whether the host will provide accommodations or financial support to the invitee during their visit
  • The purpose of the invitee’s trip and travel plans within the United States
  • Any other details confirming the invitee’s ties to their home country and plans to return

In short, the goal of the invitation letter is to provide details confirming the foreign national’s relationship with the host residing within the U.S., the dates of travel and the purpose of their visit. The letter should also include details about the invitee’s ties to their home country to verify their intent to return at the conclusion of their trip. Examples of this include information about their home, job and family.

Lastly, the host should sign the invitation letter.
