Pjing 大师， 您在课上说了， 和 F 不一样，用过 AP 之后，不是必须一定要使用 EAD，因为你的 H 被认定依然有效。
可是为什么移民局要强调“had the alien not left and returned under advance parole“才不用另办工作许可呢？刚刚用AP回来。叩谢。
"Until then, if the alien's H-1 or L-1 employment authorization would not have expired, had the alien not left and returned under advance parole, the Service will not consider a paroled adjustment applicant's failure to obtain a separate employment authorization document to mean that the paroled adjustment applicant engaged in unauthorized employment by working for the H-1 or L-1 employer between the date of his or her parole and the date to be specified in the final rule." - Q 4
