Hi Lawyer,

I am currently working on EAD with Employer A, who has filed my Green Card. It is over 2 two years since my I-140 has been approved

My current job ended, I have a new opportunity at hand with the same responsibilities as my Labour app, and the Employer B requests that I have to work on W2 ONLY. The contract is 6 - 12 months and the Employer B is willing to provide me a letter stating that the opportunity is "at-will employment arrangement to last indefinitely"

Questions:
1) What are the risks associated if I change from Employer A to Employer B.

2) Is there any limit to the number of time I can change the employers.

3) Is it mandatory for Vendor B, to file for AC21

4) Should I be concerned of a RFE/NOID and not change employers
