Interview Experience:

Interview was at 2:00 PM, we Reached and cheked in around 1:30 PM

1. Checkin at the security, airport style security
2. Checkin at the reception counter to get the token nr
3. Wait in the waiting area, After 20 mins around 2:10 PM we were called for the interview
4. Had a long walk to reach the immigration officers room, Firstly the oath to say everything true, then attorney waiver form.
After that Interviewer took pic and scanned the fingerprints. Collected our Driving Licence, EAD and passports.
5. Questions were pretty straight forward, Name, Date of Birth and other Biographic informations
6. Where were we working, current employer name and address. EVL letter and most recent paystubs
7. All the yes/no questions of the 485 form, you need to listen very carefully and then answer the questions
8. The interviewer asked for the joined tax statments, marriage certicate, birth certificate, all w2's and marriage pictures
9. Then we were made to sign the I485 forms with the count of changes that were made, we made changes to our last travel history as we had used EAD to travel recently and the latest job details
10. Then the interviewer went over the Visa Bulletin and said that our date is current

Lastly Interviewer handed over a paper stating that the case is held for review.
Then the wait game started, however surprisingly next day 10/10/2019 at 6:00 PM the status got updated to approved and new card being produced.

Tips: Dress Professionally. Prepare the photocopies of all the docs, it saves time. Organize the folder with a index number and Sticky notes stickers its really helpful.
When in Doubt ask the officer to reapeat the question or clarify it before answering anything wrong in a hurry.

This forum was really helpful in the whole journey. Thanks All. Good luck to Everyone who's waiting for the Interview.
Let me know if anyone of you have any questions.
