Family-based immigration most often involves people moving to the US to reunite with their spouse/fiancé(e) and children, or children being adopted from abroad. Per recent Department of Homeland Security data, spouses, dependent children, and parents trying to join family members in the US have median wait times of nearly a year, give or take a few months.
In other situations, family members can wait even longer. The family-based immigration process is subject to varying timelines, primarily influenced by the applicant’s relationship to a US citizen and their country of origin.
