hey u can get ur credit evaluation done here in United States. But i think it'll be better if u'll do it before u got admission into US University. U can get ur International credit evaluated through some Evaluation Company here. Just go to www.gcevaluators.com and then email them ur scan copies of original transcript. It'll cost u $160 approximately. The evaluation will be done within 6-8 weeks and then send the copy of evaluation directly to the university that u r trying to get into, then i think u can get ur transfer. Do it before issuing I20. Then it'll be easy for you to get maximum credits transfer.
