Espinoza & Molina, Corp in Chula Vista's Eastlake Business Center combines IRS Enrolled Agent tax authority with California-registered Immigration Consultant services, covering both federal return preparation and immigration-document filing from Anchorage Place. Partner Adrian Espinoza holds an EA designation and a law degree from Western Sierra Law School, enabling taxpayer representation before the IRS while his registered Immigration Consultant Bond covers document preparation — a cross-border practice that coordinates with real estate agents such as Peraza Real Estate & Associates on property-transaction tax implications for binational buyers. Partner Andrea Molina leads the individual tax division with a focus on U.S.–Mexico cross-border compliance, foreign-income reporting on Form 2555, and FBAR filings for accounts exceeding the $10,000 aggregate threshold. Mortgage applicants purchasing in the Eastlake and Otay Ranch zones route income-verification documents through origination teams at Point Mortgage Corporation after Espinoza & Molina compiles dual-jurisdiction tax transcripts. Highest-tier engagements include treaty-based return positions under IRS Form 8833, foreign tax credit calculations on Form 1116, and California Form 540NR nonresident-apportionment schedules for filers with income sourced from both sides of the border.
