Are you planning to visit the United States in 2025 on a B1/B2 visitor visa—whether it’s for tourism, family visits, or business? While not mandatory, an invitation letter can add extra credibility to your application and help you explain your reason for travel.
In this blog post, we’ll explore what types of invitation letters are acceptable, how to structure one, and whether it’s really necessary for your visa approval.
Is an Invitation Letter Mandatory for a U.S. B1/B2 Visa?
No. The U.S. Department of State clearly states that a letter of invitation is not required for a B1/B2 visa application in 2025. Applicants must qualify based on their personal circumstances, such as financial stability, employment, family ties, and their intention to return home.
However, providing an invitation letter can strengthen your case—especially if you’re staying with someone in the U.S. or attending a business-related event.
