U.S. Citizenship and Immigration Services (USCIS) is expanding its Direct Mail Program to include Form I-800, Petition to Classify Convention Adoptee as an Immediate Relative, and Form I-800A, Application for Determination of Suitability to Adopt a Child from a Convention Country. Applicants must submit Forms I-800, I-800A, and all related supplements and forms to the USCIS Chicago Lockbox facility located in Illinois, for initial processing. Applicants were previously required to file at a USCIS field office with jurisdiction over their place of current residence. The Direct Mail Program allows USCIS to process applications more efficiently by eliminating duplicative work, maximizing staff productivity, and introducing better information management tools.
