Hi I received a RFE on Jan 30.2008 and i sent all my paperwork on feb 15,2008( thats the usps delivery date) , when i call uscis help line i receive the message stating that i need to send the requested info. My question is how can i confirm if USCIS has received the RFE package that I sent them.
You say that you sent your paperwork on Feb 15th, and then say that Feb 15th is the USPS delivery date. Which is it? Did you send it on Feb 15th, or did you receive a delivery receipt notice indicating that USCIS received it on Feb 15th?
The normal way to know that USCIS received something is to send it certified with return receipt. It costs extra at the post office, but the peace of mind is worth it.
