On line of similar discussion of job change during pending I-485...
My Company A has filed I-485 on 10/08/2020. I am with them for 10 years. The client "company B" was about to file H1B transfer before my filing date became current. So I slowed down the transfer process. Now most likely I will loose the opportunity if I don't join them soon.
1. Can I initiate H1B transfer petition with Company B at this moment and join them with H1B approval before 180 days? I can do I-485J supplement and AC21 after reaching 180 days.
2. Can I initiate H1B transfer to secure the position and join Company B after 180 days on H1B or with AC21? Any risk of meddling of pending I-485 by new H1B transfer petition?
3. I asked the attorney of "Company A" who filed I-485. The answer was political in nature. The response was .... "Out of abundance of precaution, it is advisable to join after 180 days. By the time you would also get EAD." Since the attorney copied staffs of my current employer in reply, I guess he is showing loyalty for continuance of business. Based on this I halted H1B transfer petition. Not sure what is the right thing to do here. I am counting each day.
Gurus, please help with your knowledge and guidance. Sometimes attorney's suggestion becomes more confusing.
