Thai Work Permit 2025: Guide for Teachers — KET
Picture yourself strolling through Sukhothai’s ancient temples, sipping a fresh coconut, and dreaming of teaching eager Thai students in a vibrant classroom.
You’re ready to make Thailand your home, but then you hear about a work permit, and the paperwork feels like a puzzle.
Don’t worry!
Kids English Thailand (KET), based in the heart of Sukhothai, is here to guide you through securing a Thai work permit, non-immigrant B visa, and, if needed, a teaching license to teach legally in 2025.
This guide is your friendly sidekick, packed with clear steps, real links, and teacher-focused tips to turn your teaching dream into reality.
Let’s dive into the Thai Work Permit!
Why You Need a Thai Work Permit
A Thai work permit is your legal key to teaching in Thailand, issued by the Ministry of Labour’s Labour Office mol.go.th/en/. Without it, working in public schools, international schools, or language centers is illegal, and the stakes are high:
Fines: Up to 100,000 baht (about 3,000 USD).
Jail Time: Up to 5 years for serious violations.
Deportation: A ban from Thailand could end your teaching career.
With over 5,000 teaching jobs available annually, Thailand’s education scene is thriving, especially for English teachers.
A work permit ensures you’re legally employed, secures fair pay (30,000 to 150,000 baht monthly), and protects you from unethical employers who might withhold salaries.
It’s your foundation for a rewarding teaching career.
Pro Tip: Verify your employer’s legitimacy using Thailand’s Department of Business Development dbd.go.th/ to ensure they can sponsor your permit.
What Is a Thai Work Permit?
A Thai work permit is a blue booklet tied to:
One Employer: Your school or company.
One Role: Your teaching position (e.g., English teacher).
One Location: Your school’s address (e.g., Sukhothai or Bangkok).
If you switch schools or jobs, you need a new permit. It’s valid for up to one year (or shorter for temporary roles) and renewable annually at the Labour Office. You must have a non-immigrant B visa to be eligible for this application.
Key Fact: In 2025, a work permit costs 3,000 baht (90 USD) per year. I have paid 3,000 THB for over 20 years, at the local Labour Office.
Step-by-Step: How to Get a Thai Work Permit in 2025
Step 1: Land a Teaching Job
Your adventure starts with a job offer from a legitimate Thai employer, such as a public school, an international school, or a language center.
KET’s Apply page connects you with trusted schools offering salaries from 30,000 baht (public schools) to 150,000 baht or more (top international schools).
What You Need: Bachelor’s degree (any field), job offer letter, and sometimes a TEFL/TESOL certificate.
Employer Docs: Business registration, school registration (if applicable), and employment contract.
Pro Tip: Partner with a KET-affiliated school in Sukhothai for seamless permit support.
Step 2: Secure a Non-Immigrant B Visa
The non-immigrant B visa is your entry pass for working in Thailand. In 2025, the process will be entirely online via the Thai E-Visa portal, with a processing time of approximately two weeks.
What You Need:
Valid passport (with at least 6 months' validity and blank pages).
Bachelor’s degree (legalized by your home country and the Thai embassy).
Criminal background check (from your home country).
A job offer letter and the employer’s business registration.
Two passport-sized photos (4x6 cm).
Visa fee: 2,000 baht (60 USD).
How to Apply: Submit documents online 1 to 2 months before your move. After approval, enter Thailand, and your school converts it to a full work visa.
Warning: Using a tourist visa for work purposes is illegal and carries the risk of fines or deportation.
Step 3: Get a Medical Certificate
Once in Thailand, visit a local clinic to obtain a medical certificate (50 to 1,000 baht, or $1.50 to USD 30) to confirm you’re free of severe conditions, such as tuberculosis or leprosy.
Where: Clinics near your school (rural ones tend to be more affordable).
Process: Basic physical, possible chest X-ray, done in under an hour.
Validity: The permit must be recent (within 30 days) to be submitted.
Step 4: Apply for Your Work Permit
Your employer submits the work permit application to the Labour Office in your work province (e.g., Sukhothai).
You must be present to sign.
Your Documents:
Valid passport (all pages copied).
Medical certificate.
Three passport-sized photos (5x6 cm, business attire).
Employer Documents:
Employment contract.
Business and school registration.
Workplace map.
Cost: 3,000 baht (90 USD) for one year.
Processing Time: 3-7 days.
Pro Tip: Dress professionally for the Labour Office visit; it’s a quick formality.
Step 5: Keep Your Permits Active
To stay legal, maintain your visa and permit:
Visa Extension: Renew yearly at the Immigration Office for 1,900 baht (57 USD), 30 days before expiry.
90-Day Reporting: Report your address every 90 days (online or in-person) to avoid 2,000 baht fines.
Work Permit Renewal: Renew annually at the Labour Office (3,000 baht).
Re-Entry Permit: Get one (1,000 baht single, 3,800 baht multiple) if traveling abroad to preserve your visa.
Pro Tip: Combine Immigration Office visits (e.g., reporting and extensions) to save time and travel costs (100 to 500 baht).
Medical Check (A Quick but Essential Hurdle)
Before you obtain that work permit, Thailand throws a small but mandatory curveball: a medical certificate, a quirky yet critical requirement under Thai immigration law for every teacher in the country.
This document, costing ฿50-1,000 ($1.50-$30 USD), verifies that you’re free of severe conditions, such as tuberculosis or leprosy.
Think of it as a health passport to your classroom.
You’ll need to obtain this after arriving, not from your home country, as the freshness matters; Thai authorities require it to be issued in-country for accuracy.
Head to a local clinic near your Thai school or international school. It’s a quick process, often just a basic physical examination and a chest X-ray, which can be completed in under an hour for as little as ฿50 in rural areas.
In bigger cities like Bangkok, hospitals might charge up to ฿1,000 if they include blood tests, but it’s still a minor cost compared to the stakes of your teaching job.
Skipping this step isn’t an option without the medical certificate; your work permit application stalls, delaying your start date and potentially irking your Thai employer, who is eager to get you in front of students.
Timing is key: do it soon after landing, as it’s often valid for just 30 days for submission, ensuring you’re fit to inspire in Thailand’s bustling language schools or serene rural Thai settings.

Do You Need a Teaching License?
Some teaching jobs require a Teachers Council of Thailand (TCT) license:

International Schools: Often optional, with a preference for CELTA or relevant experience.
Language Schools: Rarely required.
No education degree?
