About GlobalVisaMath

Our Mission

Navigating travel rules and immigration criteria is complicated. Whether calculating the European 90/180 rule, determining Canada Express Entry CRS scores, or tracking complex J-1 visa residency requirements, mistakes can lead to travel bans or rejected applications.

We built GlobalVisaMath to provide clear, high-fidelity compliance calculations without the need for logins, fees, or data harvesting. All processing is kept 100% private, running locally inside your browser.

Trusted & Transparent Formulas

Our algorithms follow public legal guidelines and governmental instructions strictly. Below are the official sources for our models:

  • Schengen 90/180 Rules: Follows the European Parliament's Regulation (EU) 2016/399 (Schengen Borders Code) governing short-stay rolling limits.
  • Canadian CRS score: Follows the Immigration, Refugees and Citizenship Canada (IRCC) Ministerial Instructions for Comprehensive Ranking System criteria.
  • Green Card renewal: Built around the United States Citizenship and Immigration Services (USCIS) Form I-90 physical filing constraints and checklist requirements.
  • J-1 Visa restrictions: Evaluated using the United States Department of State (USDOS) Bureau of Educational and Cultural Affairs directives on active DS-2019 validation and J1 exchange program rules.

Privacy-First Architecture

The calculators run in your browser. Travel dates, scores, and photos are not sent to our server. The pages do load Google Analytics, Google AdSense, and Sentry, and those services can set their own cookies. What they collect is described in the privacy policy.
