Erkunde die Geschichte von Migration, Staatsbürgerschaft und Zugehörigkeit in Deutschland und den USA über die Jahrhunderte.
In March 1891, Congress established the Bureau of Immigration, a branch of the U.S. Treasury, to oversee immigration law and enforcement, shifting authority on matters of immigration from the state to federal level. This standardization and federalization of immigration policy has remained controversial today, especially for states along the border that would rather enact their own immigration policies.
