Ernesto Martínez is the editor and lead researcher at VisaCalc, where he oversees the accuracy of all immigration tools and guides published on the site.
He has spent more than ten years covering U.S. immigration policy as an independent journalist and researcher. His work has focused on USCIS fee schedules, regulatory changes published in the Federal Register, and the practical effects of immigration rules on Hispanic and Latino communities living in the United States.
That reporting background is the foundation of VisaCalc: a site built on the belief that immigration information should be accurate, up to date, and accessible to everyone — in English and Spanish — without paywalls or registration.
- Verifying every filing fee, eligibility rule, and processing timeline against official USCIS sources before publication.
- Monitoring USCIS.gov, the Federal Register, and USCIS press releases for policy changes — tools updated within 48 hours of any government change.
- Reviewing all immigration guides for accuracy, plain-language clarity, and bilingual consistency.
- Ensuring VisaCalc never provides legal advice and always directs users to verify information at uscis.gov.
