As i mailed all required Documents to USCIS 4 days back and i checked mail delivered next day. Till mow haven’t get any update from USCIS… how many days will it take to get case no?
i think chase one status is taking a long time these days. i am planning to go to canada for my f1 stamping.
you can call me 786-301-2359 or email email@example.com
It usually takes few weeks to get the receipt number. The processing times have been slow.
