Rangel & Associates in Chula Vista's Broadway corridor has operated as a multiservice tax and immigration-documentation practice since 2012, combining federal return preparation with ITIN applications, residency-renewal filings, and visa-consulting services from a 1010 Broadway address. The ITIN-application and immigration-form workload runs parallel to the document-processing track at Infinity Tax & Immigration Services, since both practices serve binational households requiring simultaneous tax compliance and immigration-status documentation. Federal Form 1040, California Form 540, and Schedule C self-employment returns form the core tax workload, supplemented by small-business bookkeeping and notary-public services for power-of-attorney and affidavit authentication. Apostille processing and certified translations for foreign-sourced documents require coordination with notarization specialists, a step frequently handled through Cal Notary Service in the Chula Vista market. Complex filings include multi-year back-return reconstruction for previously unfiled taxpayers, California Form 540NR nonresident allocation schedules for cross-border workers, and IRS Form W-7 ITIN-application packaging with certified passport copies and supporting identification documents.
