Please, anyone there who can give me the details of what happens at AOS Interview and also how may Interview is expected b4 GC is approved?? I need help please i need help

Go to my profile and read my interview experience , there are a lot of experiences on this website u can type AOS interview experiences on search. And yes in some instances a GC may be approved without an interview I really have not experienced that myself. The breakdown of the interview is this
1) present evidence that the marriage is not fraud
2) answer questions that the adjudicating officer may ask
3)get an approval

Hope this helps GOOD LUCK ON YOUR INTERVIEW !!!!!!!!!!!!
