hello i received my i20 last week for the Spring 2015, Can you please tell me required/necessary financial documents that I need to carry for my VISA interview at US Embassy/Consulate. Since, my brother is sponsoring me and he is located in USA, he submitted his bank details/statement for getting my i20. So what Financial documents shall I need to carry to US embassy for VISA interview. Actually some are saying that there is a high risk of VISA rejection when they know that if I establish any relation with foreign funds ( US based) because of potential immigrants. Appreciate your precious response please.
Thanks
