Family-Based Immigration Explained: Who Qualifies to Sponsor You

Immediate relatives (no annual limit)

Spouses, unmarried children under 21, and parents of adult US citizens fall into the "immediate relative" category, which has no annual numerical cap — generally the fastest family-based path.

Family preference categories (capped, longer waits)

Other family relationships — adult children of US citizens, siblings of US citizens, and most relatives sponsored by green card holders — fall into preference categories that are subject to annual limits, which can mean multi-year waits depending on the category and country of origin.

Who can sponsor whom

US citizens can sponsor a broader range of relatives than green card holders, who generally can only sponsor a spouse or unmarried children.

The financial sponsorship requirement

Sponsors generally must file an Affidavit of Support, showing they can financially support the relative above a certain income threshold, sometimes requiring a joint sponsor if the primary sponsor doesn't qualify alone.

Marriage-based cases get extra scrutiny

Because marriage fraud has historically been a concern, marriage-based cases typically involve more documentation and, often, an interview focused on verifying the relationship is genuine.

What determines your timeline

Your category (immediate relative vs. preference) and, for preference categories, your country of origin are the two biggest factors in how long the process takes.
