US Immigration Law - Explained

US immigration laws regulate the entry and stay of non-citizens. The Immigration and Nationality Act outlines four main objectives: family unification, economic improvement, refugee protection, and diversity promotion. Immigrants fall into three categories: family, employment, and refugees/asylum seekers. The visa process involves country-specific limitations and a diversity lottery. Humanitarian programs like Temporary Protected Status and Deferred Action support vulnerable groups. Lawful permanent residency, or green card status, precedes citizenship, which is harder to revoke. Understanding these frameworks is crucial for navigating US immigration.
