I was reading a lot about the SSN in this forum so I want to share my experience.
Entered the US: September 8
Called SSA for an appointment: September 10
Married: September 14 (no name change)
SSA appointment (Orlando): September 29
1st letter from SSA: October 3 (saying they were verifying my status and will let me know in written if it will not be confirmed by USCIS)
Save status changed to "case return to agency": October 14
2nd letter from SSA: October 20 (saying that my status was verified and I will receive my SSN in 2 weeks)
SSN RECEIVED IN THE MAIL: October 28
it took 4 weeks from the appointment.
