Invitation Letter

Invitation letters are not required by U.S. Embassies or Consulates in order for family members of F-1 students to obtain visitor visas. As such, ISA does not write letters of invitation for the purpose of inviting students’ family members to visit the United States.

As a courtesy to our students, ISA has provided a sample letter template for those who wish to write their own letter to invite primary family members (i.e., parents, grandparents and siblings) to the U.S. Again, this letter is not required and ISA provides this template as a courtesy only.

Should the student choose to write an invitation letter, they should also include a photocopy of their most recent I-20.
