應該沒關係, 可以用, 隨時交,

我的boston一個朋友, 在收到140rfe之前被laidoff, 140rfe 是在找新工作的途中交的, 140還是批了, 當然那時可以同時交485申請ead. 後來他就一直使用ead工作.

but.............

for you, to your safety, you need to secure a new job as soon as you lose your current one. if you can not find a new job immediately, you will lose your h1b status immediately. once you are out of status, you will have to leave here even if you have ted your 140.

if you can your 485 along with 140, the story will be different.
