Tourist Visa Extensions at Bangkok Immigration Division 1: Who Can Apply?
Bangkok Immigration Division 1 generally accepts tourism extension applications from visitors whose current permission to stay comes from a Tourist Visa or a qualifying visa-exempt entry. The standard request is one additional period of up to 30 days, but an immigration officer must approve it.
Thailand’s Immigration Bureau remains the best place to check current procedures before visiting, since requirements and local office practices can change.
Tourist Visa and Visa-Exempt Entry Explained
A Tourist Visa is a visa you obtain before traveling to Thailand through a Thai embassy, consulate, or the e-Visa system. It allows entry for tourism under the conditions shown on the visa and entry stamp.
A visa-exempt entry is different. You enter without obtaining a tourist visa in advance because your nationality qualifies for Thailand’s tourism exemption scheme. Eligible visitors receive a permitted stay at the border, subject to the current rules for their nationality and travel purpose.
Both categories may qualify for a one-time tourism extension of no more than 30 days. However, the extension is not automatic and does not give you an unlimited right to remain in Thailand. The officer can approve, shorten, or refuse the request after reviewing your documents and circumstances.
A 30-day extension is an additional permission to stay, not a new Tourist Visa.
Check Your Permitted-Until Date
Your passport entry stamp contains the date that controls your lawful stay. Look for the exact “admitted until” or “permitted to stay until” date. That date matters more than your flight booking, hotel reservation, or the expiration date printed on a visa sticker.
For example, a Tourist Visa may remain valid for entry while your actual permission to stay ends on a different date. Immigration records and the entry stamp determine how long you may remain after arrival.
Apply at Division 1 before your current stay expires. Travelers can often submit an application during the final weeks of their permitted stay, but waiting until the last day creates avoidable queue and document risks. If approval does not happen before expiry, you may face an overstay issue. Review Thailand permitted-stay dates and visa extensions before planning your visit.

Plan Around the Queue and Lunch Break
Although the office remains open until 4:30 p.m., walk-in tickets are generally available only until 3:30 p.m. Arriving early gives you more time to correct a missing photocopy, complete Form TM.7, or wait for your number. The office closes during lunch, so don’t arrive expecting continuous service between noon and 1:00 p.m.
The fee for a standard tourist stay extension is commonly reported as THB 1,900. Bring cash and confirm the current payment rules before your visit, since Immigration can change procedures. The U.S. Embassy’s Thai visa guidance also lists the 1,900-baht extension fee and identifies the Chaeng Watthana location.
What the 30-Day Extension Covers
A successful application usually adds up to 30 days to your current permitted stay. Approval remains at the officer’s discretion, and the new date is recorded in your passport.
Travelers entering under the visa-exemption scheme should also review the Thailand visa-free entry rules before applying. Your passport, entry stamp, and supporting documents must match the stay you want to extend.
Get Your Documents Ready Before You Leave
A complete document set can make your visit to Bangkok Immigration Division 1 much easier. Prepare everything the night before, then check your passport and permitted-stay date again before leaving for Chaeng Watthana.
Tourist Visa Extension Document Checklist
Bring the original passport and a separate folder containing these items:
- Complete and sign Form TM.7, the application for an extension of temporary stay. The office may provide the form, but filling it out in advance can save time.
- Attach one recent passport-style photo to the form. Bangkok Immigration Division 1 says the photo should not be more than six months old.
- Copy the passport identification page, current visa page if applicable, entry visa, and the latest entry or extension stamp.
- Include a copy of the arrival or departure card, usually TM.6, if it remains in your passport or the officer requests it. Because Thailand’s entry-card procedures have changed, carry any relevant TDAC confirmation as well.
- Bring proof of your current address, such as TM30 evidence or accommodation details, when available or requested.
- Carry 1,900 baht in cash for the standard extension fee, along with a pen.
The Thai immigration forms guide explains how TM.7 fits with other forms used during immigration procedures.
Sign every required photocopy before you arrive. Keep the original passport separate from the copies so you can present it immediately when an officer asks. Extra copies are useful if a page is unclear, missing a signature, or needs to accompany another form.
Check Your Folder the Night Before
Review the documents in this order:
- Confirm that your passport is valid and contains the relevant visa and entry stamps.
- Compare the permitted-until date with the date on your TM.7 form.
- Check that your photo is attached and every copy is signed.
- Add address evidence, TM.6 or TDAC records, extra copies, and cash.
- Pack the original passport, completed forms, and pen together.
Officers can request additional evidence or ask you to correct an application. If your documents do not match your passport or entry record, resolve the problem before taking a queue number.
Step-by-Step Guide to Extending Your Stay at Division 1
Plan your visit before your permitted-stay date expires. Tourist visa extensions at Bangkok Immigration Division 1 follow a walk-in queue process, but a queue number doesn’t guarantee same-day completion when the office is busy.
How Early Should You Arrive?
Use this order to keep your visit organized:
- Check the expiration date in your passport entry stamp. Apply before the final day of your permitted stay, because delays or document problems can create an overstay issue.
- Choose an early weekday, preferably Monday through Friday morning. The office operates from 8:30 a.m. to noon and from 1:00 p.m. to 4:30 p.m., with lunch closure from noon to 1:00 p.m.
- Go to Government Complex Building B, South Zone, on Chaeng Watthana Road. The official Bangkok Immigration contact page provides the current location and office details.
- Allow extra time for Bangkok traffic, building security, walking between entrances, and finding the correct service area. Queue tickets are listed as available only until 3:30 p.m., and a busy day may reach capacity earlier.
- Take a walk-in queue ticket, then locate the tourist extension service area. Keep the ticket visible and listen for your number.
Arriving early also gives you time to replace an unclear photocopy, correct Form TM.7, or return after the lunch closure. Appointment requirements can change, so check the official contact page before traveling. Its current information describes walk-in queue service for this process.
What Happens at the Counter?
When your number is called, submit your passport, completed TM.7 form, photo, signed copies, address evidence, and any other requested documents. The officer will compare your paperwork with your passport, entry status, permitted-stay date, and stated reason for the request.
You may answer basic questions about your trip, accommodation, intended departure, or reason for staying longer. Respond honestly and calmly. The officer might ask you to sign a page, fix an error, provide another copy, or add supporting evidence.
After submission, pay the 1,900-baht fee when instructed and wait for processing. Before leaving, check the new stamp carefully, including your name, passport number, and permitted-until date. Keep the receipt, passport copies, and any returned paperwork with your travel records.
Local Tips and Common Mistakes to Avoid
A smooth visit to Bangkok Immigration Division 1 depends on choosing the right office and arriving prepared. Small errors can cost hours, especially when daily queue tickets run out before the stated closing time.
Choose the Correct Immigration Location
Tourist Visa Extensions for Bangkok are normally handled at Government Complex Building B in Chaeng Watthana, not at every immigration counter around the city. Before traveling, confirm the office for your entry type through the official Bangkok Immigration contact page.
IT Square Laksi is easy to confuse with Division 1 because it also appears in Bangkok immigration guidance. However, Counter K there is listed for certain visa-exemption, visa-on-arrival, transit visa, courtesy visa, and APEC Business Card matters. It isn’t a general replacement for the Chaeng Watthana tourist-extension desk.
Check your entry stamp, visa category, and the current office instructions before choosing a location. Going to IT Square when your application requires Division 1 can mean losing most of a day and still needing to travel to Government Complex Building B.
Plan transportation with extra time. Traffic on Chaeng Watthana Road can be heavy, and the complex is large once you arrive. Rail connections, station names, shuttle arrangements, and road access can change, so check the route in a current map app on the morning of your appointment. Save the building, zone, and service area details on your phone.
Errors That Can Derail Your Visit
The most common problems are preventable:
- Arriving after 3:30 p.m., when walk-in queue tickets may stop, even though the office remains open until 4:30 p.m.
- Submitting Form TM.7 without a signature, complete address, or matching permitted-stay date.
- Bringing no signed photocopies of the passport, visa, entry stamp, and other requested pages.
- Leaving the original passport at your hotel and carrying only scanned copies.
- Waiting until the last day, when traffic, queues, or a missing document can create an overstay.
- Misreading the permitted-until stamp or relying on the visa’s expiration date instead.
- Assuming approval is automatic. The officer can request more evidence or refuse the application.
If your permitted stay has already expired, don’t treat the issue as a routine extension. Overstay can bring daily fines and more serious immigration consequences, including future entry problems. Review the latest Thailand overstay penalties and seek official immigration advice promptly.
Frequently Asked Questions
These answers cover practical questions that often arise after you review the Tourist Visa Extensions process at Bangkok Immigration Division 1. Rules and office procedures can change, so verify your plans shortly before visiting.
Can I extend a visa-exempt entry at Bangkok Immigration Division 1?
Yes, official guidance includes qualifying visa-exempt tourism entries among the cases handled at Government Complex Building B. However, the permitted entry period and current eligibility rules depend on your nationality and entry category. Check the latest Thailand visa-free stay and extension rules before you go.
Confirm the correct office and service area before traveling. Bangkok immigration locations can handle different entry types, so a visa-exempt entry may not follow the same process as another immigration permission.
Can I get more than one 30-day tourist extension?
The official tourism guidance describes one extension of no more than 30 days from the end of your current permitted stay. Approval is subject to the immigration officer’s review, so you shouldn’t treat the full 30 days as guaranteed.
A new visa, another type of immigration permission, or departure and re-entry may involve separate rules. Those options aren’t automatic extensions of the original tourist stay, so get current advice before making plans.
Do I need an appointment for a tourist extension?
The current official contact information describes a walk-in queue ticket service for the relevant office, rather than a required appointment system. Queue tickets are listed for weekday service from 8:30 a.m. to 3:30 p.m.
Procedures can change without much notice. Check the office’s latest instructions, holiday closures, and queue information before leaving for Chaeng Watthana.
What if my permitted stay expires before I reach Immigration?
Applying before the expiration date is the safest approach. Traffic, long queues, missing copies, or a request for additional documents can delay your application.
If your permitted stay has already expired, don’t ignore the overstay. Contact Thai Immigration or seek qualified visa advice immediately, because the consequences depend on the length of the overstay and your circumstances.
Is the THB 1,900 fee refundable if my request is refused?
Don’t assume the standard THB 1,900 fee is refundable if Immigration refuses your request. Official guidance may not explain every refund situation, and payment practices can change.
Ask the officer about the current fee and refund policy before paying. Bring enough money in the accepted form, along with extra cash for photocopies or photographs if needed.
Where can I verify the latest office information?
Check the official Bangkok Immigration Bureau website and its Government Complex contact page, FAQ, and tourist visa extension guidance. Verify the office hours, public holidays, queue rules, required documents, and fee shortly before your visit.
