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.
