How Legal Immigration Works

Legal immigration to the U.S. happens through several pathways:

  • Family-sponsored: U.S. citizens and green card holders sponsor relatives — the largest category (~65% of green cards)
  • Employment-based: Employers sponsor workers in specialty occupations, including H-1B to green card pathways (~15%)
  • Diversity Visa Lottery: 55,000 green cards per year allocated by random lottery to underrepresented countries
  • Refugees & Asylees: People fleeing persecution, admitted through overseas processing (refugees) or at U.S. borders (asylum)
  • Special categories: TPS, VAWA, U-visas for crime victims, SIJ for abused/neglected children

The Naturalization Pipeline

Green card holders can apply for U.S. citizenship after 5 years (or 3 years if married to a citizen). The naturalization process includes an application (N-400), biometrics, an English/civics test, and an oath ceremony. 9.5 million people completed this process in our data period — roughly 796K per year on average.

Temporary Visitors

Beyond permanent immigration, the U.S. admits roughly 180 million nonimmigrant (temporary) entries per year. This includes tourists (B-1/B-2), students (F-1), temporary workers (H-1B, L-1, O-1), and others. The vast majority depart on time — but about 1-2% overstay, making visa overstays a significant component of unauthorized immigration.
