What is a primary condition for eligibility for family-sponsored immigration?

A primary condition for eligibility for family-sponsored immigration is that the petitioner must be a U.S. citizen or lawful permanent resident. This requirement is fundamental because family-sponsored immigration is designed to unite family members; thus, the ability for a U.S. citizen or lawful permanent resident to petition for their relatives creates a direct family link that the immigration system aims to support.

Under U.S. immigration law, citizens and lawful permanent residents can file petitions to bring their eligible relatives to the United States. This eligibility is a core principle that underpins family reunification policies. Other conditions related to employment, passport validity, or educational qualifications do not pertain directly to family-sponsored immigration, making them irrelevant in this context. These conditions are more applicable to other immigration categories, such as employment-based immigration or international travel regulations.
