The Basics of U.S. Immigration Law

Introduction to U.S. Immigration Law

U.S. Immigration Law governs the process of entering, staying, and working in the United States. It is a complex and constantly evolving area of law that is influenced by federal statutes, regulations, and administrative decisions.

Types of Visas

Immigrant Visas

Immigrant visas are for individuals who wish to permanently reside in the United States. There are several categories of immigrant visas, including family-based visas, employment-based visas, and diversity visas.

Nonimmigrant Visas

Nonimmigrant visas are for individuals who wish to temporarily visit, study, work, or conduct business in the United States. Some common types of nonimmigrant visas include tourist visas, student visas, and work visas.

Green Cards

A green card, officially known as a Permanent Resident Card, is proof of the holder’s lawful permanent resident status in the United States. Green card holders are allowed to live and work in the United States indefinitely.


U.S. citizenship grants individuals the right to vote, participate in federal programs, hold a U.S. passport, and run for public office. There are several ways to become a U.S. citizen, including by birth, through naturalization, or by being born abroad to U.S. citizen parents.

Deportation and Removal

Deportation, also known as removal, is the process of expelling a noncitizen from the United States for violating immigration laws. Some of the grounds for deportation include criminal convictions, visa violations, and illegal entry into the country.

Asylum and Refugee Status

Asylum and refugee status are protections granted to individuals who have a well-founded fear of persecution in their home country. Asylum seekers apply for protection while in the United States, while refugees apply for protection while outside the United States.

Immigration Enforcement Agencies

U.S. Citizenship and Immigration Services (USCIS)

USCIS is the agency responsible for processing immigration and naturalization benefits, such as visas, green cards, and citizenship applications.

Immigration and Customs Enforcement (ICE)

ICE is the agency responsible for enforcing immigration laws within the United States, including the investigation, detention, and removal of noncitizens who are in the country unlawfully.

Customs and Border Protection (CBP)

CBP is the agency responsible for securing U.S. borders and facilitating legitimate trade and travel. CBP officers enforce immigration laws at ports of entry and along the border.


U.S. Immigration Law is a complex and multifaceted area of law that regulates the movement of people into and out of the United States. Understanding the basics of immigration law is essential for individuals seeking to navigate the U.S. immigration system.
