why after 180d + 180d need leave country and come back?
TLDR : Answer Summary
The requirement to leave Thailand after 180 days stems from the visa regulations in place for long-term stays, such as tourist visas. Travelers can either opt for extensions or must exit and re-enter the country to obtain a new entry stamp. Each visa type has specific rules regarding duration of stay, with some allowing only one extension per entry. This system is designed to regulate the length of stay for tourists and ensure compliance with immigration policies.
