Information verified against official sources on 24 August 2026.
This guide separates official facts from case-specific requirements. It was reviewed on 24 August 2026.
What an extension is
An extension of stay is an Immigration procedure that changes the permitted period of stay. It should not be described as issuance of a new visa.
Eligibility
The legal basis for extension depends on the applicant's current immigration status and reason for remaining in Thailand.
Documents
Passport and current immigration evidence are fundamental, with additional documents depending on the extension category and local Immigration requirements.
Address evidence
Address-related evidence may be relevant to an Immigration filing, but TM30 itself is a separate notification process.
90-day reporting
The official TM47 form confirms that 90-day reporting is not an extension of stay.
Decision
The extension decision and the period granted are determined by Immigration. Consulting and document support cannot guarantee approval.
