Can I arrange a re-entry permit at any immigration office in Thailand?

Yes, you can arrange a re-entry permit at an immigration office or at airports in Thailand. However, some immigration offices may refuse to issue a re-entry permit, requiring you to return to the office where your visa extension was granted or to obtain it at the airport when you depart. It is best to contact the specific immigration office beforehand or simply visit to determine if they will assist with the permit.
