Visa-free travel allows individuals to enter a foreign country without needing to obtain a visa beforehand. This arrangement is often based on agreements between countries, allowing citizens to visit for tourism, business, or short stays without the hassle of paperwork. Countries that participate in visa-free travel typically have mutual agreements, meaning that if one country allows visa-free entry for its citizens, the other country does the same. Popular examples include the Schengen Area in Europe, where many countries permit travel without visas for short visits, and the United States and Canada agreement for their citizens.
