The US Citizenship and Immigration Services (USCIS) is the US federal agency within the Department of Homeland Security. The USCIS is responsible for processing and giving out most of the US visas. Alongside this, it also controls and maintains the EB-5 immigrant investor program. This is the department which grants permanent residency and citizenship to immigrant investors who partake in the EB-5 program. Other roles of the USCIS in the US include modifying claims of asylum seekers, issuing certificates that give permission for the future employment of immigrants, and judging the petition or non-immigrating workers, like those with the H1-B visas. The USCIS also grants legal status or permanent residency and issues American citizenship to those who make formal applications.
