Sorry guys, forget to ask one question in previous post.
I'm ready to file AOS with I-130 (spouse of GC holder) approved last Nov after my spouse got US citizenship last week. Does anyone know how to upgrade I-130 from spouse of GC holder to spouse of US citizen? Shall I include a letter inside I-485 application package to tell USCIS the fact by attaching a copy of certificate of naturalization? Anyone has exp please share! Appreciate your answers!!
