I finally received my GC today!
Here is the timeline:
December 2: Paid Fee
February 15: POE (Newark , delayed entry for 2 years to pass)
February 24: SSN came in the mail
April 2: Card is being produced
April 10: Card is being produced (again?)
April 14: Card was mailed to me
April 15: Card was picked up by USPS (tracking number was provided)
April 16: Card arrived!
This nightmare is finally over!
For anyone who is thinking about changing the address before the card arrives, I changed my address on April 3rd, hoping this would make the card arrive at our new apartment, but I was okay with the card arriving at my husbands parents house, but since they live pretty far away I took a chance and changed the address knowing this might not work. I chatted the next day with a representative via Ask Emma and verified the address because I saw it was changed on my profile but the apartment number was missing, the representative said that he can see the apartment number and everything is okay. I had a bad feeling and submitted the AR-11 form again. the next day the apartment number disappeared from my profile again. so I verified again with a representative and they again said everything was okay.
Fast forward to today, I got a text message from USPS saying that the envelope was delivered, I went downstairs and the doorman said he can't find the envelope, it was also not in the mailbox.
10 minutes later he called me and said he found the envelope and it had a wrong apartment number on it, it was my husbands parents apartment number (the old address) and not ours.
So if you want to change the address and you are living in an apartment, you should know that there's a glitch that they don't change the apartment number (if you see the apt number vanish from your profile this means they messed up and make sure to contact USCIS to verify) but they do change the address very fast, almost immediately, I guess it's done automatically nowadays.
