1) 140有沒有expire一說,
-No.
就是說是不是必須在140 approve後若幹時間內遞485,否則會失效?
-No time limit to file I-485.
有的話,是多久?
2)如果迅速遞了485(在可能的失業前),
-if you do not change your status to another non-immigration status (e.g. H1 to H4) when you are laid off, you have to file your I-485 before you are laid off to get the AOS to stay. But you may get the RFE after you file I-485.
但由於RFE來時沒法提供EVL或者新的offer,485不幸被拒的話,以後找到工作再申請綠卡是從140重頭開始,
-No.
還是原來的140繼續有效,再file 新的485就可以了?
-Yes, but you need to have a non-immigration status or parolee status to be qualified for another I-485 filing. So, if you can change your status to H4, you may not file I-485 until you find a new job in the same/similar area.
3)EB1A的485是不是會快一些,目前大約多久啊,期間一定會收到RFE嗎?
-Case by case, but should be in a short period of time after you file I-485 because the PA is current for EB1A.
