The U.S. Immigration Framework:

The immigration system operates under federal law, managing how individuals enter the United States, how long they may stay, and what actions they can take (such as working or studying) while present in the country.

Understanding Major Immigration Agencies:

Your immigration records are typically handled by three distinct agencies under the Department of Homeland Security (DHS):

  • USCIS (U.S. Citizenship and Immigration Services): Handles domestic benefits, applications, green cards, and naturalization.

  • CBP (Customs and Border Protection): Manages border security, points of entry, and initial admissions into the country.

  • ICE (Immigration and Customs Enforcement): Handles interior enforcement, investigations, and immigration detentions.

Visas vs. Green Cards vs. Citizenship:

A Visa is a travel document allowing you to request entry into the U.S. for a specific purpose (temporary or permanent). A Green Card grants you Lawful Permanent Residence, allowing you to live and work in the U.S. indefinitely. Citizenship is the final step, granting full constitutional privileges, permanent protection from removal, and the right to vote.
