I'm getting ready to apply for the I-600A, Advance processing of orphan petition from the US Citizenship and Immigration Services.  I was surprised to learn that we have to be fingerprinted for a background check.  The fingerprinting for the home study took several months to clear because our fingerprints are so bad.  I'm really not looking forward to having to go this again.  I'm seeing that dossier preparation may duplicate some of what we did already for the home study.
