我從移民局文件查到以下答案。
in CIS Interoffice Memorandum HQPRD 70/6.2.8-P (dated 12/27/2005):
Question 11. When is an I-140 no longer valid for porting purposes?
Answer: An I-140 is no longer valid for porting purposes when:
A. an I-140 is withdrawn before the alien's I-485 has been pending 180 days, or
B. an I-140 is denied or revoked at any time except when it is revoked based on a withdrawal that was ted after an I-485 has been pending for 180 days.
據這個文件,隻要 485 pending 超過 180 天後, 原雇主無權或不能讓移民局撤消已經批準的 140. 不知是否正確。
請各位高人確認一下如果485 pending 超過180 天後換工作, 到底原雇主是否有權讓移民局撤消已經批準的 140。
