Gap in Employment during AOS

Question details

My friend lost his job on Friday when he was working on EAD (this is not the employer who has applied for GC). His i-140 was approved last year in May. He is looking for new job which would take couple of weeks. I have following question for the situation:

ANSWER

Q1. Is there any limit or restriction for number of days without work between changing job?
Ans. No. I do not believe a few weeks should make a difference.

Q2. Will this impact his GC process?
Ans. Not as long as he is eligible for AC21 portability.
