Employment Based Greencard

It's time for me to pay back to this very helpful/grateful community. I've been silent reader for this forum since I started my journey and used to read almost everyday. Reading people's experiences, useful tips gave me so much hope and guided me through what to expect and prepared me throughout during this process.
For people who are waiting after interview like me, just pray to god and eventually your day will come! I've waited almost 9 months after interview, and finally receiving it in the mail today. (Just received an informed delivery email)

Here are my Timeline, EB 3 ROW:

4/1/17 PD
9/1/17 I-140
9/15/17 I-485
10/15/17 Biometric
1/20/18 EAD/I131
4/1/18 RFE for I140
4/14/18 Responded to I140 RFE
5/1/18 I140 approved
6/1/18 Case Transferred to another office
7/1/18 Interview Scheduled
8/10/18 Interview Date

Interview was held in Chicago field office and IO was very nice and friendly. Just confirmed all the information on the I485 and asked about 10 Yes/No questions and current job description and asked few questions about how I entered in US, Port of entry and where I went to school etc..
Basically just verified all the info on the I 485.
At the end of the interview he gave me piece of paper and said his supervisor needs to review my case before he makes his final decision.
At 3 PM on same day I received an email said, Interview completed, case must be reviewed. Since then it was dead silence...
My lawyer suggested we should just wait, since we're in the normal processing time, so we didn't request info pass or anything.. In October, send out my EAD renewal form and haven't receive it yet still.

Then on 3/28/19, magic text came in "Card in Production"..
4/1/19 card was mailed to me and It's coming in the mail today.
will keep you guys posted later today.
Good Luck to you all, your day will come soon!
