c) An H-1 or L-1 holder who entered the United States on advance parole can apply for an extension of H or L status, and the approval of that extension would enable the person to return to the U.S. on H-1 or L-1 status. (To maintain that status, the person cannot seek outside employment.)
d) An H-1 or L-1 holder who travels out of the United States, and returns on advance parole, is authorized to continue working for the H-1 or L-1 employer. He/she would not be required to obtain an EAD to work for this same employer, within the validity dates of the H-1 or L-1 petition approval.
根据这两条规定,似乎使用AP回美国后,只能H1-B延期(同一个雇主),不能申请H1-B transfer. 不知道这个理解对不对?
(关于H1-B和AP的关系,还有这么多问题不知道,本来天气就热,这一急,还急出一身冷汗,呵呵~~)
