From B1/B2 to EB2-NIW — Has Anyone Successfully Filed While Visiting?

Hi everyone,

I have a question and would really appreciate insights from those who’ve done this. I’m currently in the U.S. on a B1/B2 visa and planning to pursue the EB2-NIW route. I recently got a job offer (though I know it’s not required for NIW), and my area of expertise is very niche and nationally relevant. I also have all the academic qualifications and then some so I feel like I’m a good candidate.

That said, I’m wondering: Has anyone here gone from visiting on a B1/B2 to self-petitioning for EB2-NIW (with premium processing), and filed everything concurrently (I-140, I-485, I-765, I-131) while still in valid B status?

Would love to hear about your experience — timelines, challenges, tips, and how it worked out.

Thanks in advance!
