Yesterday I decided to start my weekly/bi-weekly emails to USCIS to check on the status of our I-800. My tracking showed that they received our packet of goodies on March 2. Here is the very quick and informative reply I received from our assigned officer. He truly has been very nice to work with in the past.
After the packet is received at the lockbox in Texas, they receipt it in and put it together and send it to my location here in Missouri. Once it gets here the contract staff matches it up with the paperwork already here and then forward it to my desk for adjudication. It usually takes around 12-14 days to make it to the NBC. I will keep my eyes open for it. Thanks for the heads up.
