Hello and hope someone here was on the same boat.
I recently returned to the US after receiving an SB-1. Previous GC is an IR1 and now I'm applying for an I-90 to replace it. CBP didn't give me a new A number but stamped and endorsed my I-551.
On the I-90, I'm not sure what to put in this section:
"What is your class of admission?
Your class of admission is the 3-digit code for the immigrant category under which you were granted your permanent resident status."
Do I use my SB-1 information from here on out?
Or do I use the information back in 2011 when I was first granted a CR-1 visa? Thank you in advance for your guidance!
