# Anti-immigration **Anti-immigration** describes the political movement and policy agenda aimed at restricting immigration to the United States, encompassing both legal and unauthorized flows. While immigration restriction has a long American history — from the Chinese Exclusion Act to the 1924 national-origins quotas — the modern anti-immigration movement is most closely associated with [[Stephen Miller]]'s policy architecture within the [[Trump Administration]] and [[Steve Bannon]]'s framing of immigration as an existential cultural threat. The movement operates on multiple registers simultaneously: economic arguments about wage depression and job competition, security arguments about border enforcement and crime, and cultural arguments about demographic change and national identity. The cultural layer often shades into [[Nativism]] and the [[Great Replacement Theory]], which casts immigration as a deliberate project to dilute white political power. Anti-immigration politics has become a central pillar of [[MAGA]] coalition identity, with agencies like [[ICE]] and [[CBP]] serving as the enforcement arm of restrictionist policy.
