A Hungary Multiple-entry Tourist Visa is valid for up to 5 years from the date of issue. During this validity period, you can make several consecutive visits to the Schengen area without the need to reapply each time. However, each individual stay must not exceed 90 days within any 180-day period. The validity and number of entries granted are determined by the visa authority based on your travel history, financial standing, and the purpose of your visits. A strong and consistent travel history significantly improves your chances of being granted a multiple-entry visa.
