I just called USCIS to schedule an appointment for the stamp. My 24m extention letter expires this March. What I found out:
She said on her end the latest update on my case is that on November 14 2022 somebody is reviewing my case. Which is new to me, my last update is biometrics in April of 2021 on uscis website. However Nov-March review does sound very long.
For the infopass they said somebody should call me within 30 days... Hope this will indeed happen. Did you guys recieve a phone call sooner or later than 30 days?
And for 48M ext letters she said she doesnt know anything, in terms when will they be mailed etc, just told me to check website.
My case is on potomac Feb 2021 filer, last update April 2021 biometrics
