I have a question for my B1 B2 visa extension, I am applying for an extension because my I-94 expires on September 17 and I want to stay back till November 11 to pursue my extern ship program which lasts till November. Right now I support myself for the stay with the income from my father who works full time in India. I do not have a bank account in India and the only account I have is the Vishwa Yatra SBI prepaid credit card account to which money is added every month. I have a Bank of America account which doesn't have enough funds. I am not getting paid for this extern ship and I need to pay for my food, travel and hostel stay. Do I need a Affidavit of support from my father? Please suggest what all documents I can provide to support for my stay in the US.
