I'm on F-1 OPT with a STEM MS Degree. If I put a startup, I will be performing my roles directly related to the degree.
1) To establish employer-employee relations would having a board of directors be sufficient during STEM OPT?
2) If I apply for EB2-NIW and get I-140 approval then can I immediately shift to other non-tech roles within my startup (CTO -> CEO) Or do I have to wait for 6 months before doing that, all the while when I-485 is pending?
3) If I shift immediately and use I-485 EAD instead of F-1 EAD, then can that lead to I-485 being rejected?
Should I wait at least 6 months before using I-485 EAD? Also, if the startup fails, does that discontinue my I-485 process having approved I-140?
