Introduction

When applying for a visit visa to the United States, getting a visa invitation letter can be a huge help. The visa invitation letter is an easy but essential document that shows your reason for visiting and assures immigration officers that your stay will be temporary. Usually, a letter is written by someone who is a US citizen or lawful permanent resident and is inviting you to visit; usually, this person is a family member, friend, or business contact. The letter will generally include the writer's relationship with you, travel plans, and where you will be staying during your visit. A visa invitation letter is not a guarantee that a visa will be approved; however, it is an additional fact pointing toward your intentions and credibility in filling out the application. You can imagine it as a personal endorsement from someone in the US who is supporting your visit. Whether you are attending a family function, taking a vacation, or doing business, a legible and well-written invitation letter expresses honesty, openness, and purpose while showcasing the invitee's intent to support your efforts during the visa screening process.

When Do You Need a US Visa Invitation Letter?

If you're considering a trip to the USA, you may be curious whether or not it is a requirement to have a visa invitation letter. It is not a "required" document, but it can help strengthen your application and add a level of credibility. Think of it as extra evidence that you will actually show up and that you have a visit that has a "purpose". Below are some common usages for letters.

1. Visiting Family or Close Family Members

If you are going to visit immediate family members, such as parents, siblings, or children who live in the United States, an invitation letter from your family member can clearly define your relationship and reason for travel. It will add evidence that your visit is family-related and temporary. 

2. Attending Family or Social Events

Are you attending a wedding, graduation, or family event? An invitation letter from a host in the United States will clearly define your purpose and reassure embassy (visa) officers that you will have a home to return to after your trip. 

3. Visiting Friends in the United States

When visiting friends regarding a holiday or vacation or similar, and you have a letter from your friend explaining who you are, what you are doing, and where you are going to stay, and assuring the consulate office of your trustworthiness, transparency, and intent, it can be helpful.

4. Business or Professional Visits

If you're traveling for meetings, conferences, or trade events, you can apply for a B-1 temporary business visa for the USA with a letter of invitation from a U.S. company or organization. This professional endorsement is immensely valuable in support of your visa application.

5. Attending Educational or Training Programs

When you are invited to participate in a short course or seminar, or invited as an exchange participant, or invited to a brief instructional program, a letter of invitation from the educational institution or professional development organization may be helpful, as it will explain what you are doing, for how long you will be staying, and assure officials that your visit is exclusively for education or professional development.

6. Medical Treatment Visits 

If you are traveling for a medical care event, an invitation or confirmation letter from the US hospital or clinic is often needed. The letter will typically describe your treatment plan and stay.

7. Travel for Tourism Purposes with Accommodation provided by a US Resident

In tourism-related trips involving visits to family or friends, a tuition letter can add legitimacy to your travel purpose, especially when visiting top places in the USA for travelers. An invitation letter helps support your accommodation information and adds more details to your travel plans.

8. Supporting a Weak Application

If you have limited travel history or are concerned that ties to your home country will not be obvious, an invitation letter provides assurance. An invitation letter shows that the planned visit is authentic and well-supported.

Who Can Write an Invitation Letter?

When you are asked to apply for a US visa, the invitation letter can be helpful to your case, but it is also essential to understand who is able to write one. To be effective, the letter must be provided by a credible, trustworthy person in the United States, and below are some examples of people who can write it, along with why they qualify.

1. US Citizen

US citizens can write invitation letters for family, friends, and colleagues who are temporarily visiting. Their US citizenship brings legitimacy and confirmation that their visit has a legitimate American contact who supports the trip.

2. Lawful Permanent Resident (Green Card Holder)

Permanent residents can write the letter as well. They should include proof of residency status, such as a green card, their contact information, and details of the invitation.
