American immigration policy refers to the laws and regulations that govern how individuals from other countries can enter, live, and work in the United States. This policy is shaped by various factors, including economic needs, humanitarian concerns, and national security. It includes pathways for refugees, asylum seekers, and temporary workers, as well as family reunification processes. The policy is enforced by agencies such as U.S. Citizenship and Immigration Services (USCIS) and Immigration and Customs Enforcement (ICE). Changes in immigration policy can occur due to shifts in political leadership and public opinion, impacting the number of immigrants allowed and the criteria for entry.
