Can I Apply for a Visa Extension While My Current Visa Is Still Valid?

Yes, you can apply for a visa extension while your current visa is still valid. There is no requirement to wait until it is close to expiry. Thai Kru Visa Agency regularly assists customers whose visas expire in a few weeks and proactively arranges the necessary appointment.

The Specifics

• Extensions are possible for Tourist Visa, Visa Exemption, Non-O Retirement, Medical, Guardian and Marriage visas.
• You may submit your application even when your visa expires soon, for example on 21 November or 10 November.
• For the first extension of a 90-day Non-O Retirement Visa to one year, you must show 800,000 Baht in a Thai bank account held for at least two months before applying.
• Non-O Retirement and Non-O Marriage Visas must initially be applied for outside Thailand; you cannot convert a Tourist Visa to a Non-O Visa while inside the country.
• Required documents include: the first page of your passport, all Thailand entry and exit stamps, TM30 proof of accommodation (obtained from your property owner, manager or hotel), and for Medical extensions a doctor’s note stating the appointment and reason to stay longer. Non-O Retirement extensions also need an updated bank statement covering the last three or six months.
• Service fees start at 7,000 Baht for Tourist or Visa Exemption extensions (typically granting 30 additional days), 9,000 Baht for Medical Treatment, and 12,000 Baht for Guardian or initial Non-O applications (plus 80 USD embassy fee paid directly by the customer). The Non-O Retirement service fee has increased due to stricter documentation requirements.
• Once you pay, the team sends a secure upload link, checks your documents, books the immigration appointment and can accompany you to the office.

Expert Tips from Thai Kru Visa Agency

Send your documents early so the team can review them thoroughly and secure the best available appointment. If you already have a current TM30 for your address there is no need to update it. For Non-O Retirement extensions, keep the required bank balance stable; any recent large transfers may need extra explanation.
