Family-Based Immigration: Petitioning for a Relative

Family-based immigration lets U.S. citizens and lawful permanent residents petition for certain relatives to immigrate. It's the most common path to a green card, but how long it takes depends enormously on the relationship and, for some categories, the country the relative is from.

Immediate relatives vs. preference categories

Spouses, unmarried children under 21, and parents of U.S. citizens (if the citizen is 21 or older) are "immediate relatives" — there's no annual cap on these visas, so processing is generally faster. Everyone else falls into numbered "preference categories" (adult children, siblings of citizens, spouses and children of permanent residents), which are capped each year and can involve waits of years, sometimes decades for siblings from high-demand countries like Mexico or the Philippines.

The basic process

The petitioning relative files Form I-130 to establish the relationship. Once approved, and once a visa is available for that category, the relative either adjusts status from inside the U.S. (if eligible to do so) or goes through consular processing at a U.S. embassy abroad. Along the way, USCIS also requires a financial sponsor to sign an affidavit of support, showing the immigrating relative won't become a public charge.

Common complications

Problems tend to show up around prior unlawful presence (which can trigger multi-year bars to reentry), marriage-based petitions where the government suspects the marriage isn't genuine, and any past criminal or immigration violation. These aren't automatically disqualifying, but they change the strategy — sometimes a waiver is available, sometimes the timing of when to file needs to be planned carefully.
