Tonga

Tonga maintains a relatively open visa policy, especially for short-term visitors from a wide range of countries. Many nationalities, including those from the United States, Canada, the United Kingdom, Australia, New Zealand, and most European Union member states, are granted visa-free entry or a visa on arrival for stays typically up to 30 days, which can often be extended. This policy aims to encourage tourism and facilitate travel to the Pacific island nation. It's crucial for travelers to check the specific requirements for their nationality before planning their trip, as policies can vary and are subject to change. Tonga is not part of any major visa-free agreements like the Schengen Area, as it operates its own independent immigration system.
