Family-based immigration is a pathway that allows U.S. citizens and lawful permanent residents (Green Card holders) to sponsor certain family members for immigration to the United States. This process is rooted in the principle of keeping families together and is one of the most common ways individuals immigrate to the U.S.

There are two main categories:

1. Immediate Relatives – includes spouses, unmarried children under 21, and parents of U.S. citizens. There is no cap on the number of visas issued in this category.

2. Family Preference Categories – includes more distant family relationships, such as adult children or siblings of U.S. citizens, and spouses or unmarried children of Green Card holders. These categories have annual limits and may involve long waiting periods.

Sponsors must meet certain income requirements and agree to financially support the relative to ensure they do not become a public charge. Once approved, family-based immigrants can obtain a Green Card and eventually apply for U.S. citizenship if eligible.
