Adjustment of Status - I-485

Thank you so much to everyone who shared their experiences, it definitely helped with my expectations. I would like to share mine experience now. First of all, if someone is doubting if they can do everything by themselves, I would say - you totally can! We were a little worried, cause everyone would ask us if we had a lawyer and we did almost everything on our own. We received an advice from a notary which actually created more problems for us, as he did more mistakes in our paperwork if we did everything on our own.

So our case is based on marriage, here is our timeline:

12/22/2015 - sent a package with these documents: I-130, my and husband's G-325, I-485, I-765, I-864, copy of Marriage certificate, my and husband's birth certificates, My visa copy, Copy of front page of my passport, Stamp in passport, My work petition, I was here on L visa, husband's tax return, husband's W2, my I-94, my 2 photos, Check $1490. I didn't have my medical exam at a time of sending the paperwork.
12/28/2015 - Priority date
01/07/2016 - Check cashed
01/13/2016 - Received receipt confirmations from USCIS (I-797C for employment authorization and Adjustment of status case), possibly letters arrived earlier, but we were out of town. It looks like USCIS received all our docs on 12/28/2015 and mailed the notifications on 01/07/2016
01/23/2016 - Received a letter for biometrics appointment, the letter was sent on 01/20. Appointment was for 02/03/2016. Went to do my biometrics in Elisabeth NJ, was 10 min late, but they let me in. I filled out an application form, my last name and middle name on the form was changed by ASC manager due to taking husband's last name. The whole procedure of finger prints and photo took 2 hours
02/04/2016 - Received a letter of a Request for Initial Evidence that was mailed on 01/29/2016. The form that we filled out has expired, so we had to fill out a new one with a new expiration date
02/22/2016 - got a notice (dated 2/16) from immigration hat they haven't received my medical exam and to wait until further notice when to send it or show it during interview
02/24/2016 saw an update on the website that they are ready to schedule an interview
03/26/2016 - Received EAD card
07/27/2016 - Interview appointment text received, interview for 8/30
on 8/30 had the interview in Newark, NJ. we had to wait for 2 hours before we got called in. The officer was nice and said it won't take too long. We had to swear that we are saying the truth. He checked our driver's licenses, asked for passports, birth certificates, marriage license. He asked my husband - how we met, when did we exchange our contact information, when approximately we started dating, when was our first date, what did we do on our first date if we went for ice cream afterwards. If we had a wedding, and we had religious or civil ceremony and if we had a honeymoon. In our case we didn't, cause we had a family emergency, so we had to cancel or plans. He also why we got married in NC if we live in NJ, but we explained that's where we lived at a time. He asked who attended the court with us. Then he asked me about my application, my full name, my husbands name, the address, my and my husband's date of birth. Also just standard questions "Yes/No" where they ask if you had any criminal activity etc. He asked where I worked and what was my position. When was the last time I entered USA and through what port and under what status. He didn't ask me anything about our relationship with my husband. Then he asked for supportive documents, as lease, correspondence, bills on the same name, insurance, pictures. He kept all of it, so make sure you have a copy of the pictures somewhere, because you won't get them back :) He asked if we have a bank account together and we don't, because we like to have our finances separately. Then he said that we are done and if we had any questions for him. I asked when will we get an update and he said that it usually takes around 2-4 weeks. We also offered to show him scrapbook that I made from years ago, but he said that it's not necessary and that he got all the information. Overall, I had an impression that it didn't go too well cause we didn't have normal things that I guess happen for the couples who got married and my husband (probably because of stress) was very short and dry with the answers. And officer didn't ask me anything about our relationship... But we'll see, I hope we had enough proof that we have a true marriage.
09/06/2016 - received texts that the case was approved and also got notices in the mail
09/08/2016 - got an update that the card was mailed
09/20/2016 - received my card in a mail

Yay! So happy! We are finally relieved with my husband.

Good luck to everyone.
