Many international students have family members who consider visiting the United States (for example, to attend your graduation) and, to do so, many will need to apply for visitor visas to enter the United States. At many US embassies and consulates, applicants for visitor visas are recommended to submit a “letter of invitation," confirming the legitimate basis for the applicant’s visit to the US. These letters of invitation for the families of international students and international family members of domestic students can be written by you, the student.
To compose the letter yourself, it is recommended that you include: your name, school, relationship to the applicant, name of applicant, applicant’s country of citizenship/permanent residency, dates expected to visit the United States, duration of visit, preferred arrival date, and how the applicant will be financially supported during the visit. The letter should be addressed to the specific US consulate or embassy where your family member will be applying for their visitor visa.
