A visa extension in Phuket adds time to your current permission to stay in Thailand, and it is filed at the Phuket Immigration office. A tourist stay can usually be extended once for 30 days, and long-stay visas such as the O or retirement visa are extended yearly. Apply before your current stay ends, never after.
An extension of stay is one of the most common visa tasks in Phuket, and also one of the easiest to get wrong. The rules depend on the type of stay you hold, your nationality and what you can prove at the counter. A missing page or a form filled in the wrong way can cost you a wasted trip across the island.
We prepare your documents, confirm the requirements for your exact stay type and handle the submission. You receive your passport back with the new stay stamp and a clear note of your next deadline.
This is for you if
- You are on a tourist stay or visa exemption and need more time in Phuket.
- You hold a Non-Immigrant visa (O, B, ED, O-A or O-X) and need your yearly extension.
- You want your next deadline tracked so you never overstay.
- You prefer not to queue at the immigration office or fill in forms yourself.
This may not fit if
- Your stay has already expired by many days. Contact us first, because overstay needs a different approach.
- You need a different visa category altogether. We will advise you in the pre-check.

The Phuket Immigration Office
Extensions are handled at the main office in Phuket Town. What that means for your visit is in our Phuket Immigration Office overview.
Which stays can be extended?
A tourist stay can usually be extended once for 30 days at a Thai immigration office. Stays based on a Non-Immigrant visa (family, marriage, retirement, work or study) are extended for a longer period, typically one year at a time, if you still meet the conditions. Some stay types, such as visa-exempt entries, have their own limits.
Because the details change, we always confirm the current rule for your case before preparing anything.
Why timing matters
Apply for your extension before your current permission ends. Overstaying carries a daily fine and can lead to an entry ban if it goes on for long. If your date is close, send us a message right away and we will tell you what is realistic.
Extension of stay and 90-day reporting
Staying more than 90 days in a row triggers the 90-day report. We include reminders and filings in our 90-day reporting service, so your extension and your reports stay in sync.
Documents for an extension of stay
The exact list depends on your stay type. For a tourist extension we usually prepare:
- Passport with the current stay stamp and a copy of key pages
- Extension application form (we complete it with you)
- Recent passport photo
- Accommodation confirmation, TM30 or a registered address
- Proof of funds where the stay type requires it
- Copy of your departure card information, if applicable
What affects your quote
This service is quoted on request, with our fee and the government fees shown separately. See how our quotes work. The government fee for the extension is charged at cost and is shown separately.
- The stay type you hold and what you want to extend it to
- Whether your documents are complete
- How close your deadline is
- Whether you also want 90-day reporting handled
Common mistakes to avoid
- Waiting until the last day, so any missing document becomes an overstay.
- Arriving without an accommodation confirmation or a registered address.
- Using an outdated form version or copies that are not readable.
- Assuming the extension changes your visa type. It only extends the stay.
Frequently asked questions
How long can I extend a tourist stay?
In most cases a tourist stay can be extended once for 30 days. The rules of the day apply, which we confirm in your pre-check.
How long does an extension take?
Often a few business days from submission, depending on the immigration office workload. We tell you what to expect for your case.
Do I need to be present at immigration?
Often yes, depending on your stay type. We tell you in advance and keep your visit as short as possible.
What if I already overstayed?
Contact us immediately. Overstay is handled differently from a normal extension and the earlier we speak, the better.
Can you extend my retirement or marriage stay?
Yes. Long-stay extensions are part of our work. We check the financial and relationship documents before submission.
Is the 90-day report part of this service?
It is a separate task, but we can handle both together so no date is missed.
