Hi guys, how is it going? I am trying to file the I-912 form to waive U.S citizenship fee. The problem is I don't know how does it go. Anyone in here had or has tried to fill this form out? My concern is I don't know what address should I send to (I already read but couldn't see anywhere). Secondly, do I have to fill out I-912 first and then send out to wait for approval then fill out N-400 for U.S citizenship? Or do I fill out both of them at the same time? Inside the I-912 form, I don't see any blanks for asking what fee do I want to waive or anything like that. How do they know that I'm asking for N-400 fee waiver?
