The following is quoted from your blog. " 1) 你 H-1 入境后为新的雇主工作，其 I-129 transfer 获得了 USCIS 的批准；"
Questions:
1. Doesn't it mean I-129 MUST BE APPROVED before I come back to the states.(I won't work for old company at all after come back to U.S.)
2. Using AP to come back and won't work for old company at all, what will happen to me:
* if my H1 transfer still pending?
* if I only file H1 transfer right after coming back U.S. and dirctly work for new company?

"移民局的规定是，使用 AP 入境，只要仍然维持 H 身份，其 H 身份可以 transfer (H-1)，也可以 extend (H-1/4)，－－就象你没有用过 AP 一样。
"an alien who was an H-1 or L-1 nonimmigrant, but who was paroled pursuant to a grant of advance parole, may apply for an extension of H-1 or L-1 status, if there is a valid and approved petition. " - Q 3 of INS Memo (5-16-00) H/Ls Who Work After Entering on Advance Parole（下同）
这个仍然维持 H 身份，不只是说你 H-1 入境后继续为原来的雇主工作，或 H-4 入境后仍保留其 H-4 身份，还应该可以这样引申诠释如下：
1) 你 H-1 入境后为新的雇主工作，其 I-129 transfer 获得了 USCIS 的批准；"
