The Schengen Area, which consists of 26 European countries, requires travelers to have travel insurance before granting them a visa. This requirement ensures that visitors have sufficient coverage for medical emergencies, repatriation, and other unforeseen events during their stay. The Schengen Area countries include popular tourist destinations such as France, Italy, Germany, Spain, and Greece. It is important to note that the minimum coverage required is €30,000 ($35,000) for medical expenses, and the insurance should be valid for the duration of your stay.
