What is the government organization that oversees an individuals immigration status?
The United States Citizenship and Immigration Services (USCIS) bureau of the Department of Homeland Security (DHS) is the main organization charged with overseeing immigration. Many of the USCIS’s duties were formerly handled by the Immigration and Naturalization Service (INS). The Department of Labor is also involved in some stages of employment-based immigration (such as reviewing requests for labor certification), as is the US Department of State (issuing visas).
