Immigration law


Immigration law refers to national government policies controlling the immigration and deportation of people, and other matters such as citizenship. Immigration laws vary from country to country, as well as according to the political climate of the times, as sentiments may sway from the widely inclusive to the deeply exclusive of new immigrants.

Immigration law regarding the citizens of a country is regulated by international law. The United Nations International Covenant on Civil and Political Rights mandates that all countries allow entry to its own citizens.

Certain countries may maintain rather strict laws which regulate both the right of entry and internal rights, such as the duration of stay and the right to participate in government. Most countries have laws which designate a process for naturalization, by which foreigners may become citizens.

During the colonial period, independent colonies created their own immigration laws. The first law governing the naturalization of foreigners was the Naturalization Act of 1790. The 1882 Chinese Exclusion Act was passed to stop the immigration of Chinese people. The Emergency Quota Act of 1921 and the Immigration Act of 1924 put a quota on how many immigrants were permitted, based on nationality and the numbers of persons who had immigrated in previous years. The Immigration and Nationality Act of 1952 led to the creation of the Immigration and Naturalization Service.

The Department of Homeland Security, which replaced the Immigration and Naturalization Service, enforces immigration laws. The United States allows more than 1 million undocumented immigrants to become Legal Permanent Residents every year. The United States also issues more Visas than any other country in the world.
