_Interview experience_
The interviewer is a Caucasian lady at her 50s. She was very intimidating at first.
She asked us if the information on the I-485 application is correct. Then went over yes/no question on the I-485.
After that, she started asking question about us.
1. Where did we live? Who were our roommates? How to spell their names?
2. What schools did we graduated from? What year?
3. Where did we work? What are the occupations? Explained what we did for the company.
4. Why did we decide to get married? When and where?
She took pretty long on those questions thou. I felt like it was half an hour. Then our lawyer reminded her that we also brought photo album, joint documents if she want to take a look at them. She looked at them, pointed at few pics and asked who were those ppl in there.
Then she looked at our graduation photos and asked how did we feel when we were in school. My spouse had a little chit chat with her about career wise. Then she said we could go, she had to do a background check before making her decision, also told me to remove the conditions after 2 years.

The day after, I got a text msg noticed me that they ordered my card. The next day is another notice saying that my case is approved.

Let me know if you have any questions about the process. I'm more than happy to answer.
Thank you,
