Can I leave Thailand with a re-entry permit during the 90-day Non-O retirement visa period?

The question addresses the possibility of leaving Thailand during the 90-day period of a Non-O retirement visa with a valid re-entry permit. Community members confirm that it is indeed possible to leave as long as a re-entry permit is obtained before exiting. They mention the process of obtaining the permit at immigration, either at the airport or the local immigration office, and highlight the associated costs. It's important to note that failing to acquire a re-entry permit before leaving will result in the visa becoming invalid.
