Adjustment of Status - I-485

Interviewed today Holtsville Long Island at 8 am ,so I think I’m the luckiest girl in the world I’m still in disbelief so waited about an hour and a half got called got sworn in and the IO basically asked the questions from the back of the packet then she went straight into saying I because I’ve been married for 4 years I would get a 10 year green card and after 3 years I can file for citizenship then she spoke for the next 10 minutes about what to look for on the citizenship test and explained in details for 10 minutes when I tell you I have a duffel bag full of paperwork n she didn’t even look she didn’t ask us 1 question NOT ONE !!!!! Then she said I will make a decision at the end of the day look out for mail within 2 to 4 weeks ..! My marriage is more than legit but to no even get one question is just shocking! So they pretty much had everything they needed from me in the first packet I sent .
