The United States of America is recognised as a nation of immigrants and has a long history of immigration. People from all over the world have travelled to the nation in search of better prospects, safety, and the ability to start new lives. Here are some facts about immigration to the United States:
The entry, residence, and naturalisation of foreign people are governed by an extensive body of immigration laws in the United States. The Department of Homeland Security's (DHS) US Citizenship and Immigration Services (USCIS) is primarily responsible for enforcing these laws.
People can enter the United States through a number of different visa categories. These consist of immigrant visas (for people planning to live permanently in the United States) and nonimmigrant visas (for brief stays related to travel, employment, research, or business).
Foreign nationals can live and work permanently in the US with the help of a "Green Card," also known as a "Permanent Resident Card." Common ways to receive green cards include family sponsorship, job possibilities, refugee or asylum status, or other unique situations.
