The U.S citizenship and Immigration Services plays a central role in the EB-5 process by administering and adjudicating all aspects of the program. USCIS is responsible for reviewing the initial immigrant petition (FORM I-526) submitted by the investor to ensure that the investment meets all program criteria including the required capital investment and the job creation mandate. Once the petition is approved, USCIS also processes the application for conditional permanent residency ( Green Card) and later reviews the petition (Form I-829) to remove the conditions on residency by confirming that the investment has been sustained and the required jobs have been created. Additionally, USCIS oversees regional centers by approving and monitoring them, ensuring that projects funded through these centers comply with program regulations and contribute positively to economic growth. 

This comprehensive oversight helps maintain the integrity and effectiveness of the EB-5 Immigrant Investor Program.
