Come in here, Mr. Pjiang

Hi, PJ, this is quoted from your blog http://blog.wenxuecity.com/blogview.php?date=200706&postID=42162

"移民局的規定是，H 簽證使用 AP 入境，隻要仍然維持 H 身份，則不必進入 AOS 狀態。其 H 身份可以 transfer (H-1)，也可以 extend (H-1/4)，就象你沒有用過 AP 一樣。"

I would treat this "H 簽證" as H1B Petition Approval Notice (I797), not H1B visa stamping (you get this from US embassy). But I could not find the same rule from here the INS Memo (5-16-00):

Please correct me if I am wrong.
