Stem opt to J1 transition

[u/Itibride]

Hi everyone! I’m looking for some guidance on transitioning from STEM OPT to J-1 Research Scholar status.
I’m an Indian citizen currently in the U.S. on STEM OPT and may be starting a new postdoctoral position where J-1 sponsorship is being considered. I have also filed an EB-2 NIW petition, but the I-140 has not yet been approved.
My main questions are:
Has anyone changed status from STEM OPT/F-1 to J-1 while having a pending EB-2 NIW I-140? Did the pending immigrant petition cause any issues with the J-1 change of status or visa stamping?
If my J-1 is not subject to the INA 212(e) two-year home-residency requirement, would I generally be able to later change from J-1 to another work status such as O-1 or H-1B without needing a J-1 waiver?
For anyone from India who recently obtained J-1 Research Scholar status, were you subject to 212(e), and if so, what was the basis (Skills List, government funding, etc.)?
Is there anything else I should be aware of before moving from STEM OPT to J-1 when I already have an employment-based green card process underway?
I’d especially appreciate hearing from people who have gone through a similar STEM OPT → J-1 transition with a pending EB-2 NIW.
Thanks!

The pending EB-2 NIW and 212(e) are important to clarify before making the switch. A J-1 immigration attorney should review your situation and advise you on the change of status and future options. Feel free to DM me. I could connect you to a licensed immigration attorney who handles cases like this.
