USCIS San Diego at Sommerset Plaza on Chula Vista's Broadway processes immigration and naturalization cases for San Diego County's South Bay communities. The federal field office adjudicates Form N-400 naturalization petitions and Form I-485 adjustment-of-status applications, with immigration attorneys at The Law Office of Giovanna Gallo representing applicants through interviews and oath ceremonies. Applicants attend this location for naturalization interviews, InfoPass appointments, and document requests covering family-based and employment-based petition categories. Community integration resources for newly naturalized citizens connect through regional nonprofits including South Bay Community Services, which provides resettlement and social support across the South Bay. The office adjudicates cases under Title 8 of the Code of Federal Regulations, covering petition categories from immediate-relative sponsorship through EB-1 and EB-2 employment preference classifications and diversity visa lottery selections.
