Thanks for your help.
A chinese register agent contacted me, informing they can register US company for me and open East West Bank.To open the account, I should go to their china branches and do necessary, and they can make USA account.Frankly, i don't know if they can manage the account 100% successfully, as i had bad experience in opening offshore account for my island company in mainland China. A very bad condition is China policy changes from time to time, making businessman insane... That's why I want to make a US company with US account.
