What is an invitation letter for US Visitor visa (B1/B2), and how do I write one?
If you have a friend or family member coming from another country to visit you in the United States, you might be asked to write an invitation letter. Although not a requirement, an invitation letter from a US citizen or legal permanent resident (LPR), can strengthen your B visa application. Invitation letters are helpful because they detail that you will have a place to stay, sufficient financial support, and a definitive departure date.
