回复：有稳定的H1, 还用EAD干嘛

First of all, thanks to you,toosad for your reply. Actually I read Pjiang's article of AP/EAD many a time, yet feeling not that for sure... and clearly, for example, once AP used, Ok for dependent,yet not proper for principle applicant, and AP needs annually renewable,dosen't it? With H1/H4 at hand,could we still travel outside of USA?
