Avalos Professional Services in Chula Vista's Third Avenue Village provides immigration document preparation, SENTRI applications, and dual-citizenship processing for cross-border clients. Mexican dual-citizenship filings require apostilled documents and certified translations, services that parallel the document authentication work at Interdocpro. The Latina-owned firm prepares Global Entry and SENTRI Trusted Traveler applications, including CBP reconsideration petitions for previously denied applicants. Clients establishing U.S. business entities through the firm often need Individual Taxpayer Identification Numbers, a filing coordinated with enrolled agents at Chula Vista CPA. SENTRI reconsideration filings prepared by the firm compile CBP Form 823 declarations, supporting I-94 travel histories, and federal background-check clearance packages for submission to the Otay Mesa enrollment center.
