Update.
I just received an email from USCIS that the card for I-765 was ordered for production and that she should receive it within 30 days. Now onto the interview for GC
Just came back from the interview. The appointment was on time and the case was approved. My mom will receive the card within 2 weeks. They changed the policy and they no longer put a stamp in the passport. They have a new form they need to fill out by hand.
Waiting for the plastic card in the mail
Thanks guys for all the help.
