Green Card Wait Time Calculator

The history behind the Green Card Wait Time Calculator traces back through the following developments. The 19th century was largely an era of open borders for international migration. The United States imposed almost no restrictions on European immigration, and tens of millions moved across the Atlantic seeking economic opportunity. Ellis Island processed over 12 million arrivals between 1892 and 1954. The Chinese Exclusion Act of 1882 was a notable exception, marking the first significant federal restriction based on national origin. World War I disrupted migration patterns and introduced passport requirements that had not previously been systematically enforced. The postwar period brought the Emergency Quota Act of 1921 and the Immigration Act of 1924, which established national-origin quotas explicitly designed to favour Northern and Western European immigrants while severely restricting arrivals from Southern and Eastern Europe and virtually banning Asian immigration. World War II generated massive displacement. The 1951 UN Refugee Convention, drafted in its aftermath, established the legal definition of a refugee and the principle of non-refoulement, prohibiting return of refugees to places where they face persecution. It remains the foundational international instrument governing refugee protection. The US Immigration and Nationality Act of 1965 abolished national-origin quotas, replacing them with a preference system favouring family reunification and skilled workers. This fundamentally redirected immigration flows toward Latin America and Asia. The Schengen Agreement of 1985, implemented in 1995, eliminated passport controls between participating European nations, creating the world's largest free movement area. The September 11, 2001 attacks triggered sweeping security reforms. The Department of Homeland Security absorbed immigration functions, biometric data collection became mandatory, and visa screening intensified significantly. Brexit in 2020 ended UK participation in EU free movement, prompting the introduction of a new points-based system in January 2021. Post-COVID, many countries accelerated digital nomad visa programs to attract remote workers, creating a new visa category requiring its own set of income threshold and duration calculations.
