My wife's I-130 had been approved. I've just paid the AOS fee and hoping to send my completed I-864. Hopefully all things will go well and I belive my wife and daughter will migrate successfully. Unfortunately I will be out of the country for the most part of the next 5years. The question is_ Can my wife(principal applicant) file for naturalization after 5yrs without me getting involved? Or, is it only the me (petitioner) that can file for naturalization?
