What does American immigration supervision mean?

American immigration supervision is a means for the US Immigration Bureau to control and manage the entry and residence status of foreigners, and its purpose is to ensure the national security and public interests of the United States. The target groups of immigration supervision include illegal immigrants, those with expired visas and those who violate the provisions of US immigration laws. In the process of immigration supervision, the Immigration Bureau maintains the national security and social order of the United States by issuing punishment, detention and deportation.

The specific measures taken by the US Immigration Bureau include, for example, confirming immigration status through entry and exit documents such as passports and visas, and monitoring and mastering the whereabouts and activities of foreigners, so as to timely discover and deal with illegal immigration, illegal employment and other violations of immigration laws. In specific immigration control measures, immigration officials usually investigate, intercept and interrogate suspicious persons to ensure the authenticity and legality of their identity information and immigration status.

American immigration supervision is an important tool for the US government to cope with the challenges brought by global immigration and international personnel exchanges. Immigration supervision can ensure the legitimacy and effectiveness of the immigration system, safeguard public interests and social order in the United States, and prevent and combat terrorist activities. At the same time, entry-exit supervision also provides foreigners with a fair, transparent and legal living and working environment, and creates a more stable and safe environment for international cooperation and exchanges.
