Dear Sir/Madam,
I,
During their stay in United States, I will bear all responsibilities including, but not limited to, financial responsibilities, return air ticket fare to travel from Vietnam to USA and back, travel expense within USA, medical insurance, housing and food. I will personally make sure that they leave United States before the expiration of their authorized stay. I will also personally make sure that they will not become public charge on the part of United States Government.
So I respectfully request you to grant my parents’ visitor visa.
Thanking you,
Yours Sincerely,
