EAD (WorkPermit)

Hi everyone, I am an applicant for AOS
I just got my combo card in mail in Sep 7th last week.
However I’m waiting for my Social Security Card which my lawyer said it’ll be arrived in the mailbox in a week after I received my combo card.
So today it’s been a week and I still didn’t see any SSN envelope.

Short story I reached out to my lawyer and she suggested me to reach out to SSA, however I talked to SSA and they want me to submit my application in person.
And bring few documents
-original brith certificate
-EAD card etc

I don’t have the original birth certificate with me at the moment so I’m worried if I can’t apply for SSN with that but somehow I used it for AOS and it was fine.

Is there any of you receiving the SSN in the mailbox ?
Or experiencing this SSN process without showing the original birth certificate?

I’m leaving abroad in 2 weeks so I need to get it done as soon as possible so my spouse needed to submit his Tax by October though I know to have the SSN in hand will takes few weeks.

Thanks guys!
