Family-based Immigration

Family-based immigration is the system that lets U.S. citizens and lawful permanent residents petition for certain relatives to live in the country permanently. It covers spouses, children, parents, and siblings, though the rules and waiting times differ sharply depending on the exact relationship and the immigration status of the person filing.

Categories and preferences. Not every family relationship is treated the same way. Immediate relatives of U.S. citizens generally face no numerical limits, while other relationships fall into preference categories that are capped each year, creating long queues that move at different speeds depending on the category and the relative’s home country.

Backlogs and life changes. Because demand in many categories exceeds the annual limits, cases can sit in line for years, and events like a petitioner’s death, a beneficiary’s marriage, or a child turning a certain age can change or even end eligibility while a case is pending.

Sponsorship responsibilities. A petitioner does not just start the process; they typically also take on a financial commitment to support the relative once they arrive, a responsibility that can carry legal weight long after the green card is issued.
