Frequently Asked Questions
Are my inputs stored or shared?
No. GlobalVisaMath operates strictly client-side. The tools process all dates, education parameters, and trip details in your local memory, and nothing is transmitted to any server.
How accurate are the calculator results?
Our logic matches official legal guidelines: EU Regulation (EU) 2016/399 for Schengen, the standard IRCC Express Entry Comprehensive Ranking System point allocation for Canada, and USCIS Form I-90 / USDOS exchange visitor directives. However, they are for informational purposes and do not represent formal legal advice.
What is the Schengen 90/180 rule?
Under the Schengen Borders Code, non-EU travelers are allowed to stay in the Schengen Area for up to 90 days in any rolling 180-day window. This calculation requires looking backwards 180 days from any single day of evaluation.
