FINALLY Received Birth Certificates and Marriage Certificate

Fed Ex brought our birth certificates and marriage certificate today. We're ready to mail off the I-600A Application for Advance Processing of Orphan Petition. However, we are questioning if we need to mail in the $70 each for fingerprinting with it. The cost for mailing this out is $525. Total for us would be $665. Also the application mentions we should have the home study approval. We heard we didn't need that yet. I'm also trying to find out more on this. Hopefully some of the yahoo groups I'm on will email me back this morning with the information.
