Hello there!
My permanent resident card expires on June 8. I mailed my joint package on March 9 and it was delivered to the Carol Stream PO Box on March 11.
I think I messed up and filed too early. Even though it got delivered within the 90 days, I've been reading the horror stories of people getting their packages back 4 weeks later after their packages got delivered 1 day after their 90 days start. I still haven't received it but I'm ready for the disappointment. I'm dumb for rushing. Should've mailed it on March 11. Don't make the same mistake!
Anyway, I want to hear about your timelines. Since there is no March thread, I started this one.
Good luck everyone!
