You CAN change to a different job whenever you want to, but you need a new PERM and I-140 for your 485. For changing to a same or similar job after your 485 pending 180 days, you don't need re-apply a new PERM and I-140.
【在 S*********e 的大作中提到】 : 想想这same or similar的要求听ridiculous的,几年来,谁兴趣没有个变化?能力没 : 有个变化?这不是限制人才吗?难道有机会大幅的提高薪资都不行?
