Adjustment of Status - I-485

Hello, I just had my interview so I wanted to share my experience. I am Canadian, I married a US Citizen and applied for a marriage based greencard. My paperwork was sent to the MSC service center. I have lived in the USA for 4 years before getting married and applying. I have been here legally working on work visas. We have been together now for over 6 years and lived together for 5 years. We were married on Jan 27th 2017. We used a lawyer to help with our application.

Timeline:

Received EAD: May 2nd 2017
Notice for Interview: December 19th 2017
Interview Date: January 26th 2018

On the day of the interview we arrived an hour early, waited 2.5 hours before we were seen. With us I brought the following:

marriage certificate
my current passport and last passport
my husbands passport
my long form birth certificate
my husbands long form birth certificate
my EAD
my NY Driver's liscense
my husbands drivers liscense
my social security number card
my husbands social security number card
all immigration-related documents i have ever received (greencard + work visa paperwork)
shared health insurance
shared dental/vision insurance
shared Amex bill
paper work showing i am the beneficiary of his 401k
shared utility bill
pieces of mail showing that we share the same address
both of our most recent W2s from the last 2 years
2 months of pay stubs for us both
a letter from his employer verifying employment
shared cell phone bill
3 photo albums of pictures from travel and our life (we have visited about 20 countries together)

I was wrongfully arrested 8 years ago so i also brought the original paperwork from that.

She officer was not overly nice. She didn't ask us a lot of question but seemed like our pictures. She only asked each of us:

How we met
She asked me what my husbands full name was, his birthday and what he does for work.
She asked him what my name was, my birthday, and what I did for work.

That was all she asked.

She looked through our paperwork for a bit, asked to keep a couple pictures, and kept all my copied of documents.

She seemed really confused over the arrest paperwork, i told her the charges were dropped because they had no evidence and it was a wrongful arrest (this happened in canada) and that it should be outlined in the paperwork there. She couldnt properly read the paperwork so she said she had to send it to "council" and that they will "call canada".

She then handed us a letter said we will get an answer in 120 days and that they never do approvals on the spot. The whole interview was probabaly about 15 mins, max.

My EAD expires in 90 days so im a bit nervous.

I would love any feedback people have on this. I don't know if it went good or bad. I keep reading that some people get approved on the spot and get the GC shortly. Others get this letter and months later have still not heard anything.

We are a super convetional couple, our lawyer told us we were a slam dunk and had nothing to worry about. but now im nervous. i think this wrongful arrest is really screwing us up.

Any idea what i should now expect to happen????
