Except tax documents, leases, and deeds, all papers must be originals. Copies are rejected and returned. Every dollar of needed support must be proven through student bank statements, proof of the sponsor's income, or a lease or deed. Each dollar not provided by the student personally, must be promised in an affidavit by a sponsor. We do not care how many sponsors there are, whether or not they are U.S. citizens, or where they live.
Students can sponsor themselves either partly or in full.
No affidavits are needed for the student's own money. Recent bank statements in the student's name must be provided, and statements from at least a year earlier to show us that the money was not borrowed and recently deposited. Remember, however, that the law requires financial support for your entire program in addition to readily available cash for the first year. Unless you have enough cash to support yourself and your studies in the U.S. for your entire program, your cash will soon be used up. You will probably need a sponsor with an income to show that you can finance the entire educational program.
