I got my gc through eb2 niw, but i have a phd. If the person just had bachelor, looking at how things are, i would say pretty sure denial.

But that would be 140 denial not 485 and if it was based on niw, the officer would have argued the endeavor is not in national interest.

If it was not niw and did perm certification and went all the way to interview, something doesnt add up. If there was problem with application, it wouldnt have gone all the way through. If it was denied in interview, must be some issue with lying in the application, off school working f1, dui etc et
