回复:Request Help:job change
Your NIW is not sponsored by any specific employer. Sure you can change job anytime, the only requirement is that you stay on the career path outlined in your I-140 material.
If your approved I-140 is EB3 or EB2-1, then file I-485 now. You can change job after 180 days of I-485, but the new job has to be a similar position.
