1 File 485後馬上換工作,如果原來公司不revoke 140,真的等180天後就可以transfer 485到新公司嗎?
Yes. Google the AC21 memo.
In such a case, you need to use H1 transfer instead of EAD. Using EAD is illegal before 485 has been pending for 180 days.
2 怎樣才能不讓原來公司不revoke 140?
As far as I know, good relationship is the only way. Revoking I140 or not doesn't matter to the employer at all. It's up to them to play this stupid game.
3 新公司工作和原來的很不一樣怎麽辦?
This is tough. Job deions have to be similar.
I know a guy who changed a job and the job deion was matched exactly word by word. You got it?
