What is USCIS?

Another acronym you may see being thrown around a lot online. It stands for US Citizenship and Immigration Services. You can find their website at http://www.uscis.gov/portal/site/uscis . You will need to go through them to file your I-600A form, I-600 form, and Adjudicate Orphan Status First Petition (AOF). You can go to their website to download the forms and instructions that you need.
