I600A - Application for Advance Processing of Orphan Petition

So my I600A application should be delivered to the USCIS on Friday 4/1/11.  It seems funny that I never gave the United States Immigration office a second thought before this...now I'm wondering how many people must work there!  Once our home study is complete, I will send that in and they will send me the coveted I171-H.  :)
