非常感謝老師。如果我沒有理解錯的話，我可以這樣做： 如果原公司同意出具Employment letter說可以在拿到綠卡後繼續雇傭我，我仍然可以通過他們辦理485，
然後在180天後用EAD自由轉換到現在公司？這樣的做法是合理的麽？
-The I-140/I-485 can not be portable to your new employer (you can not use AC21 benefits) because you file your I-485 after you left the I-140 sponsor. So, if the old company (I-140 sponsor) has financial problem (no ability to pay) from the date of PERM filing to the date of I-485 approval, your I-485 will be denied. So, you had better ask your current employer to file a new PERM/I-140 for you just in case.
