The Schengen 90/180 rule, explainedHow the Schengen 90/180 rolling window works for non-EU travelers, what counts as a Schengen day, multiple-passport myths, overstay penalties, and the difference from tax residency.
US federal tax residency for non-citizensHow the IRS decides if a non-citizen is a US tax resident: the Substantial Presence Test, the green-card test, visa day-counting (F-1, J-1, H-1B), first-year choice, the closer-connection exception, and the exit tax.
