NIW was not employer sponsored, i.e. you can file NIW without employer's support. Once your NIW being approved, you can change your job (in the same area) at any time without permission of your current employer. For PERM, you should stay at your current position for at least 180 days after I-140 approved, then you can change your job (in the same area as well).
