The permitted stay on a tourist visa varies by country and the visa type issued. In many destinations, tourist visas allow stays of 30 to 90 days per entry, though some countries grant longer durations or multiple entries over six months to a year. The visa’s validity and length of stay are determined at approval or by border officials upon entry. Travelers must respect these limits, as overstaying can lead to fines, deportation, or restrictions on future travel. Always confirm the exact conditions printed on your visa.
