If you have a relative in the USA and you feel like the pweson can pay the 400 USD on your behalf,there is no PROBLEM.Just let me know as soon each payment is made.Please note that you only need to pay only about 50 usd to the school for the schoo to issue you the letter of offer and when the letter of offer is issued,you can then o ahead with the other stage of paying for 100 usd deposit and 250 usd for SEVIS(TO THE USD Government coffers).
