Hi,
I am thinking of applying from Vietnam. I am a US citizen with a American Passport wanting to apply for DTV for medical treatment. My husband and 2 children (3 years and 4 months old) are Bangladeshi passport holders. Will they be eligible for the spouse and children DTV visa? I will be the primary visa holder. How long will the total process be for myself and my family to get the visa if i apply from Vietnam? Will it be quicker in any other country?
