Business & Employment 
Non-Immigrant B Visa
The Non-Immigrant B (Business) Visa is the primary pathway for international professionals and entrepreneurs looking to participate in Thailand's dynamic economy. Whether you are being relocated by a multinational corporation in Bangkok or launching your own startup in Phuket, this visa provides the essential legal framework for your professional stay.
Securing a Non-B visa is a critical milestone that allows you to apply for a Thai Work Permit, open comprehensive business bank accounts, and establish long-term roots for yourself and your family in the Kingdom.
📍 Crucial Notice on Immigration Autonomy
Every immigration office in Thailand operates with a degree of localized autonomy. While the general rules apply nationwide, specific offices may ask for additional documents, different formatting, or change their required checklists without public notice. It is absolutely vital to verify the current, exact requirements directly with your local immigration branch or your designated legal service provider before filing any paperwork.
Which Visa Do You Actually Need?
With recent updates to Thai immigration law, many professionals are confused about which visa fits their needs. Here is a definitive comparison to ensure you are on the right track:
🏢 Non-Immigrant B (Work)
Best for: Local employment & Business Owners.
- You are hired by a company registered in Thailand.
- You are setting up a Thai Limited Company to run a local business.
- You will be earning a salary paid in Thai Baht and paying Thai taxes.
- Requires a formal Thai Work Permit.
💻 Destination Thailand (DTV)
Best for: Remote Workers & Digital Nomads.
- You work for clients or a company located outside of Thailand.
- You do NOT have Thai clients and do not earn money locally.
- You only need a visa to live in Thailand while working on your laptop.
- Does not require (or allow) a Thai Work Permit.
❤️ The Marriage Alternative (Non-O)
If you are legally married to a Thai citizen, you do not necessarily need a Non-B visa to work. You can apply for a Non-Immigrant O (Marriage) Visa. A Work Permit can be obtained while holding a Non-O visa! In fact, doing so cuts the company's burden in half: the registered capital requirement drops to 1 Million THB, and the ratio drops to 2 Thai employees per foreigner.
The Complete Non-B & Work Permit Process
To legally work in Thailand, securing the visa is only phase one. You must seamlessly transition from entering the country to securing the Work Permit and extending your stay. Below is the standard, chronological process.
1
Company Eligibility (Prerequisites)
Before an employer can sponsor your visa and work permit, they must meet strict criteria:
- Must be a legally registered company with the DBD.
- Registered Capital: At least 2 million Baht (fully paid up) per foreign employee.
- The 4:1 Ratio: Must employ and pay social security for at least 4 Thai staff per foreigner.
- Must have a physical, verifiable office address (not a virtual office).
2
Apply for Form WP.32 (Outside Thailand)
While you are still in your home country, the employer submits documents to the Ministry of Labour to secure a WP.32 Approval Letter. This is essentially a pre-approved work permit required by most embassies to issue your initial visa.
3
Apply for the Non-B Visa
Armed with the WP.32 letter and a massive stack of corporate documents from your employer (DBD registration, shareholder lists, balance sheets, VAT Phor Por 20, etc.), you apply for the Single-Entry Non-B Visa at the Thai Embassy (often via the E-Visa portal). You must also show personal adequate finance (20k THB).
Processing Time: 1 to 3 Days (Once documents are accepted).
4
Enter Thailand (90-Day Stamp)
Upon arrival, Immigration will stamp your passport giving you an initial 90 days. You cannot legally start working or receiving a salary yet.
5
Obtain the Formal Work Permit
Within 15 days of arrival, you and your employer must visit the Department of Employment. You must bring your passport, 3 photos, and a Medical Certificate (issued in Thailand covering 6 prohibited diseases: leprosy, TB, drug addiction, alcoholism, elephantiasis, stage 3 syphilis).
Once the Work Permit is issued, you can legally begin work and must be registered with the Social Security Office (SSO) within 30 days.
Processing Time: 7 Days (approx.) via www.doe.go.th
6
Extend Visa to 1 Year
Before your initial 90 days expire, you return to the Immigration Bureau. The company must prove it has paid tax and social security for you and its Thai staff. Upon approval, your visa is extended for 1 year from the date of entry.
7
Ongoing Maintenance (Re-Entry & 90 Days)
- Multiple Re-entry Permit: Apply for this immediately. If you leave Thailand without it, your hard-earned Non-B visa is cancelled instantly.
- 90-Day Reporting: You must report your address every 90 consecutive days. You have a window of 15 days before and 7 days after the due date to file.
The Executive's Real Estate Strategy
For many professionals on a Non-B visa, property investment is both a lifestyle choice and a business necessity. Being on a work visa offers unique advantages for property buyers:
■ Bank Account & Financing
Holding a Work Permit makes you eligible to open "Resident" Thai bank accounts. This significantly simplifies the transfer of funds for a property purchase in Sukhumvit or Pattaya and can even open doors to local mortgage options for long-term workers.
■ Corporate Housing vs. Private Ownership
While your company can rent an office or house, foreigners still prefer to own their residence personally. Purchasing a condominium allows you to build equity during your years of working in Thailand, rather than paying rent to a landlord.
Work Visa Myths
- Myth: I can work on a Non-B visa without a Work Permit. Fact: No. The visa only gives you permission to stay. Working without the actual Work Permit booklet (or digital equivalent) is illegal and can lead to deportation.
- Myth: If I quit my job, I can keep the visa until it expires. Fact: Your visa extension is tied to your employment. Once your job ends, your visa is technically cancelled that same day. You must leave or secure a new visa immediately.
What to Do & Avoid
- Do: Transfer your visa if you get a new passport. If you get a new passport, you must visit Immigration to physically transfer your visa stamps and your re-entry permit.
- Avoid: Performing work not listed in your permit. Your work permit is specific to the company, location, and job description listed. Performing different duties at a different branch without an update is a violation.
Frequently Asked Questions
1. Does the Non-Immigrant B visa allow me to work immediately?
No. The visa only permits you to enter and stay in Thailand. To legally work, you must separately apply for and receive a physical or digital Thai Work Permit from the Department of Employment.
2. What is the 4 to 1 Thai-to-Foreigner employment ratio?
For every one foreign work permit issued, a standard Thai company must employ four full-time Thai nationals and pay their social security contributions. This is a fundamental requirement for most visa extensions.
3. How much registered capital is needed for a work permit?
Generally, a company must have at least 2 million THB in fully paid-up registered capital to support one foreign work permit. If the foreigner is married to a Thai national, this capital requirement is often reduced to 1 million THB.
4. Can I buy a condo as a business owner on a Non-B visa?
Yes. Foreigners can purchase and own freehold condominiums in their personal name regardless of their visa. However, holding a Non-Immigrant B visa makes the banking and transfer process much more streamlined.
5. Can my family join me on my Work Visa?
Absolutely. Your legal spouse and children under 20 can apply for a Non-Immigrant O 'Dependent' visa. This grants them the same length of stay as your Work Visa extension, allowing your family to live together in Thailand.
