There is an annual cap of 10,000 applications under the EB-5 program.[citation needed] The U.S. Citizenship and Immigration Services (USCIS) has offered its EB-5 Immigrant Investor Program since 1990. It is designed to encourage foreign investment in infrastructure projects in the U.S., particularly in Targeted Employment Areas (TEA), high unemployment areas. The funds are channeled through agencies called regional centers, now designated only by the U.S. Department of Homeland Security.
