United States Citizenship and Immigration Services collects fees for all applications because fee revenue funds the majority of its operation, according to yearly budget summaries. There is no form I-30; but Petition I-130 pertains to the legal immigration of alien relatives.
USCIS outlines a prospective operating budget of roughly $4 billion In the FY2016 Homeland Security budget request. Of that sum, less than $130 million is supplied by the discretionary spending of the federal government. Revenue from fees provides the additional billions to fund the agency's seven major divisions, such as Service Center Operations and Fraud Detection and National Security.
