Passports and visas were not required for entry to America, rules and procedures for arriving immigrants were determined by local ports of entry or state laws, and processes for naturalization were determined by local county courts. In the course of the late 1800s and early 1900s, many policies regarding immigration and naturalization were shifted, in stages, to a national level. Court rulings giving primacy to federal authority over immigration policy, and the Immigration Act of 1891, led to the establishment of the U.S. Bureau of Immigration and the opening of the Ellis Island inspection station in 1892. Constitutional authority (Article 1 \u00A78) was later relied upon to enact the Naturalization Act of 1906 which standardized procedures for naturalization nationwide, and created the Bureau of Naturalization (initially joined with the Bureau of Immigration; later -from 1933 to 2003- both functions were part of the Immigration and Naturalization Service). After 2003, the Immigration and Naturalization Service split into separate agencies under the then newly created Department of Homeland Security: Naturalization services and functions have been handled by U.S. Citizenship and Immigration Services (USCIS), immigration services and regulations have been divided between administrative (in USCIS), enforcement (within in Immigration and Customs Enforcement), and border inspections (under U.S. Customs and Border Protection)."@en . . .
