Immigration Site

Hello,
Ive been married for 6 months now and we had our AOS interview at the end of July.
We got seperated right away, I got called in first, asked question for 15-20 minutes (everything was recorded on video) and then my wife got called in, took a seat right next to me and was asked the same questions.
The questions were like; what we did yesterday, how we met, who was present when we first met and so on... Of course our answers matched, we were unsure in like one question. After this the Immigration Offcier started to go through our pictures asking us where they were taken. She was flipping through our joint documents, which we unfortunately didnt have too many (because of my lack of SSN, we couldnt have a joint lease, life insurance...). She got "angry" at us and said: "Is that all you have???". I was like, sorry, this is all. She acted like She didnt want to approve my case the whole time. The interview lasted for about 45-50 minutes. I was sweating in the last 10. She started to flip through all the papers again, while She sighed big, like She wants this day to be over already. She printed out a paper and handed it to me, it was a RFE asking for three affidavits that know us as a couple and must be notarizad. We were given 30 days to fulfill the request. Of course I sent in the three letters the next week but I havent heard anything from them since then. The online tracker is still at "Inital Review" both on the I-130 and the I-485 status.
When can I expect something from them? Why were we interrogated like this? Were both white, Im 27, my wife is 25 no cultural or relgion differences or anything like that. Im just really nervous, even though I sent in the RFE papers, Im not so sure now that we are going to get approved. Has anybody experienced anything like this on this forum?

You just had an I/O who probably had greasy burritos for lunch. It seems that your marriage is real, so you have nothing to worry about. If you dont get any response within 30 days, do an infoPass appt to check on it.

Is this for your I130 or I751?

First thing is, yes you were unfortunate enough to get a difficult I/O. Sorry about that

Secondly, people here often say that lease and joint bank account and other legal/financial documents are the strongest evidence. I had no SSN either but my spouse was able to add my name to the existing lease and existing bank account, so that we have joint accounts. Im sure many banks allow that - it took like 10mins for us to do that. We were able to add my name on electricity bills and stuff, and life insurance. In the worst case, if you have a second interview or they ask for more documents, you should try to get those.

Lastly, (this is just my guess), probably they randomly choose a certain percentage of people to do video recording and separate interview, for quality assurance purpose? Otherwise, do you think theres anything in your application/circumstance that may raise a red flag?
