One of North Park's bilingual tax preparation and immigration document offices operating since 2010, Larios Income Tax and Immigration is based at 3317 El Cajon Blvd in San Diego's 92104 ZIP code. Clients with immigration cases requiring legal review are often referred to nearby attorneys such as the Law Office of Josefina Carrillo, Esq. for representation beyond document preparation. Staff hold IRS Annual Filing Season Program credentials, meeting continuing-education requirements for federal tax return preparation and limited IRS representation rights. The firm also maintains an office in Tijuana, providing cross-border service for dual-citizenship and SENTRI/Global Entry applicants who pair filings with bookkeeping support from firms like Sirius Accounting Solutions. The most complex engagements involve simultaneous individual and small-business returns combined with ITIN applications and naturalization petition preparation for multi-generational households.
