How to Renew Your Thailand Travel Visa: A Step-by-Step Guide

If you need more time in Thailand, the path forward is straightforward but often misunderstood. Most travelers either extend their stay from within the country or apply for a new visa from abroad, and choosing the right option can save time, money, and unnecessary stress. This guide walks through both routes step by step, based on current Thai government procedures, so you can act with clarity and avoid common pitfalls.

The short answer

Renewing a Thailand travel visa usually means one of two things:

• Extend your current permission to stay inside Thailand at an Immigration office using Form TM.7 and a 1,900 THB government fee. 
• Apply for a new visa from outside Thailand through the official Thai e-Visa portal and travel in on that visa. 

Below you will find precise, step-by-step instructions for both paths, plus arrival card requirements, timing rules, and what to do after a rejection.

Step-by-step: Extend your stay inside Thailand (TM.7)

Most travelers on visa exemption or a tourist visa can request a 30 day extension at a local Immigration office. Requirements and the fee are standardized nationally.

1. Confirm you are eligible

• You must apply while you still have valid permission to stay.
• Typical tourist extensions add 30 days. Special cases like medical treatment have tailored document lists. See the government guide for tourism extensions.
  
  • English guide: Application to stay in Thailand for tourism purposes. 

2. Prepare your documents

• TM.7 application form. Download
• Passport biodata page copy, latest Thai entry stamp, and current visa or permission stamp.
• One 4x6 cm photo taken within 6 months.
• 1,900 THB fee in cash. For the official checklist, see the government’s tourism extension page above or local Immigration handbooks. 

3. Go to a Thai Immigration office

• Offices are open on business days and process most tourist extensions the same day. Bangkok’s main office is Immigration Division 1 at Chaeng Watthana; provincial offices handle local applications.

4. Pay the government fee

• The nationwide fee for an extension of temporary stay is 1,900 THB.

5. Receive your result

• If approved, you will get a new “permitted to stay until” date stamped into your passport on the spot. Keep copies of your new stamp.

6. If you plan to leave and re-enter Thailand before your new end date

• Protect your stay with a Re-entry Permit so your extension is not voided when you depart. Fees are 1,000 THB for single and 3,800 THB for multiple re-entry. You can apply at Immigration or at some international airports before departure. Official handbooks:
  
  • Re-entry permit guide
  • Government fee list

Expert tip from Smart Visa Travel: apply one week before your current permission expires. That timing leaves room to fix document issues or queue delays without risking overstay.

Step-by-step: Apply for a new Thailand visa from outside Thailand (Thai e-Visa)

If you will be outside Thailand or your situation requires a fresh visa, use the official e-Visa system managed by the Ministry of Foreign Affairs.

1. Create an account and choose the correct visa type

• Official portal: https://thaievisa.go.th. Many embassies confirm that all Thai visas are now filed online through this system.

2. Upload documents and pay online

• Follow the official user manual for document formats and naming.

3. Wait for processing and receive your stickerless e-Visa by email

• Print or save the approval email to show airlines and Thai Immigration on arrival, as embassies advise.

4. Avoid common errors that trigger rejection

• The MFA highlights frequent mistakes that lead to cancellation or refusal, including name format and passport number issues. Example guidance: “Common Mistakes in applying for Thai e‑Visas.”

Smart Visa Travel note: Processing times and requested evidence vary by embassy and your nationality. Apply well in advance of travel.

Thailand’s arrival card requirement in 2026: TDAC replaced the paper TM6

Thailand replaced the old paper TM6 with the Thailand Digital Arrival Card (TDAC) on May 1, 2025. All non‑Thai nationals must complete TDAC before entry. Submit within 3 days of your arrival date, download the QR code, and present it at Immigration. 

What you need to complete TDAC

• Passport details and personal information
• Travel details and accommodation in Thailand
• Health declaration items required by the Ministry of Public Health
• One email address to receive your TDAC
• You can file as an individual or file a group submission for up to 10 travelers
• You can update certain fields anytime before travel Official TDAC manual sections “Preparing Information” and “How to use system” confirm these points. 

How long the arrival card is valid after submission

• TDAC is tied to your specific trip and is intended to be submitted within 3 days of arrival. It remains available to download or print for the duration of your stay in Thailand. If your arrival date changes or falls outside the original window, submit an update or a new TDAC before you travel. See the official manual guidance on 3 day timing, updates, and downloading your card. 

Security reminder

• Use only the official Immigration Bureau portal that ends with .go.th. TDAC is an immigration declaration, not a visa, and the official site provides it directly. Official manual note: “Please note that the Thailand Digital Arrival Card is not visa.”

Key rules that affect timing and compliance

• Overstay penalties: 500 THB per day, capped at 20,000 THB. Serious or long overstays may trigger bans. Thai Immigration handbooks and government sources confirm the fine level.
  
  • Examples: local Immigration guidance and BOI summary. 
• Re-entry permits: Required to keep a single‑entry visa or extension valid after you leave and come back. Official fees are 1,000 THB single and 3,800 THB multiple, per TM.8. Government handbooks and fee lists confirm this. 

Practical timelines we recommend

• 7 to 10 days before your current stay ends: file a TM.7 extension at Immigration if you plan to remain in Thailand.
• 3 days before you travel to Thailand: submit TDAC online and save the QR code to your phone and as a printed backup. 
• 3 to 6 weeks before your flight if you need a new visa: apply through the official e‑Visa portal and monitor for any embassy requests for additional documents. 

Using a reputable facilitator

Smart Visa Travel does not process applications. If you prefer a supported experience, a secure and legitimate third party like iVisa can help you assemble and submit visa applications and checklists with a user friendly interface. Expect to pay a service fee in addition to any Thai government fee. Start here: https://www.ivisa.com/.

For arrival cards, use the free official TDAC portal listed above. Avoid paid “arrival card” sites that do not end in .go.th. The TDAC manual confirms the official government domain and that TDAC is an immigration declaration, not a visa.

FAQs

What are the requirements for completing a Thailand arrival card?

Complete TDAC online within 3 days of your arrival date. Provide passport, trip, accommodation and required health declaration details. You can submit as an individual or create a group submission. Download the TDAC for presentation on arrival. 

Can I renew my Thailand visa before it expires?

Yes. You should file your TM.7 extension while your current permission to stay is still valid. For a standard tourist extension, bring TM.7, one 4x6 cm photo, passport copies, and pay the 1,900 THB fee at Immigration. 

How long is a Thailand arrival card valid after submission?

TDAC is trip specific. Submit within 3 days before arrival, then keep the TDAC QR code available during your stay. If your arrival timing changes outside the original window, update or resubmit before travel. Official manual notes timing, updates, and download availability. 

My Thailand visa was rejected. How do I reapply?

Read the refusal notice and correct the exact issue before submitting a new application through the official e‑Visa portal. Embassies emphasize using the portal, following the user manual, and avoiding common document errors that cause rejection.

If your timing is tight and you are eligible to enter visa‑free, consider entering on visa exemption instead of awaiting a new e‑Visa, then applying for a 30 day extension inside Thailand. Always confirm your eligibility and current rules with the official sources linked above.
