Sending documents during potential government shutdown!

Hello,

I am getting ready to send my removal of condition documents to the government but I am slightly concerned. There are talks of a potential government shut down.

Does anyone know what could even happen if I send the documents and the government shuts down before they reach the correct location? Will my papers be lost?

Should I send my removal of conditions now, worried that they may close or should I send them between January 9 and 20 (after I come back from a trip)?
