U.S. Family-Based Immigration Policy [February 9, 2018]   [open pdf - 976KB]

"Family reunification has historically been a key principle underlying U.S. immigration policy. It is embodied in the Immigration and Nationality Act (INA), which specifies numerical limits for five family-based immigration categories, as well as a per-country limit on total family-based immigration. The five categories include immediate relatives (spouses, minor unmarried children, and parents) of U.S. citizens and four other family-based categories that vary according to individual characteristics such as the legal status of the petitioning U.S.-based relative, and the age, family relationship, and marital status of the prospective immigrant."
