Wait
If you file for NIW now and get a NIW, you may get a GC only if you stay in the same geographic location for 5 years. If you move to a different area after your residency and that area is MUA/HPSA, you still can count the earlier 4 years from your residency, but must refile your NIW. Therefore, I don\'t see an advantage in filing now. If in the 4th year of your residency, you get an offer from a MUA/HPSA that appeals to you, file your NIW from that job-even if it\'s a fellowship. The other option is get the right job and go with labor-it is likely to be faster in the future with PERM.
