Visa and Work Permit Services in Thailand Explained

Thailand's immigration framework for foreign professionals is built around two interconnected documents: a Non-Immigrant B (business) visa issued by the Ministry of Foreign Affairs, and a work permit issued by the Ministry of Labor. Foreign nationals need both before they can legally work in Thailand. The visa authorizes the stay; the work permit authorizes the specific job at the specific employer listed on it.

As an established work permit agency in Thailand, we guide foreign employers through each step: 

• Before arrival: the employer prepares the non-immigrant B visa invitation documentation, typically including registered capital confirmation, employee ratio compliance, and job description.
• On arrival: the employee applies for the work permit in Thailand, with the employer providing corporate documents, financial statements, social security registration, and tax documents.
• Ongoing: renewals, address changes, 90-day reports, re-entry permits, and changes to job scope or employer must all be filed with the correct authority within strict deadlines.

Missing a deadline or filing with an incorrect document set can lead to fines, permit denial, or in some cases, deportation of the employee, so most foreign-owned employers appoint a specialist provider to manage the process end-to-end.
 

Corporate Visa & Work Permit Service in Thailand for Companies

For employers in Thailand, setting up a foreign hire involves company-side conditions as well as employee-side paperwork. Thai law requires the employing company to meet minimum registered capital (generally 2 million baht per foreign employee), maintain a ratio of four Thai employees to each foreign employee (waived or reduced for BOI-promoted companies), and be current on tax, VAT, and social security filings before a work permit can be issued.

As a consultant for work visa matters in Thailand, our team coordinates the corporate file (company registration, financial statements, VAT certificates, social security records) alongside the employee file (passport, degree certificates, employment contract, medical certificate) so both halves of the application arrive in order. We also advise on alternatives for companies that do not meet the standard ratios, including BOI Smart Visa applications, LTR (Long-Term Resident) visas, and EEC (Eastern Economic Corridor) special visa categories where appropriate.

Frequently Asked Questions

Q: How long does it take to process a visa application?

A: The processing time for a visa can range from a few days to several weeks, depending on the visa type, the business 

Q: Can I extend my visa while in the country?

A: You can extend your visa in the country before it expires. The process involves submitting an application to the immigration office along with any required documents based on the type of visa (tourist visa, work visa, or dependant visa).

Q: How much does a visa cost?

A: Visa fees vary depending on the type of visa. Some countries charge additional service or processing fees.

Q: What is the difference between a single-entry and a multiple-entry visa?

A: A single-entry visa allows you to enter a country once. After you exit, you cannot return without a new visa. A multiple-entry visa allows you to come and go from the country multiple times until the visa expires.

Q: Do I really need a visa agent in Bangkok, or can I apply on my own?

A: Individuals on simple tourist or short-term visas can generally apply directly through a Thai embassy or online e-visa portal. For business-related applications, Non-Immigrant B visas, work permits, LTR visas, permanent residency, or any renewal involving a company sponsor, using a visa agent in Bangkok is usually the practical choice. A specialist agent checks that corporate documents meet current Labor Department expectations, files within the right deadlines, and handles in-person appointments where required. Immigration requirements are amended frequently, and a single missing document can trigger a rejection that delays the start date by weeks, so most foreign-owned employers in Thailand engage a professional visa agent to manage the process.

Q: What information do you need from my company to start a work permit and visa process?

A: To begin a work permit and visa process, we typically need your company affidavit and shareholder list (issued within the last six months), VAT registration certificate (Por.Por.20), the most recent audited financial statements, social security registration documents, evidence of Thai-to-foreign employee ratio compliance, the employment contract or offer letter, a detailed job description, and organizational chart. From the foreign employee, we need a passport copy, recent photographs, highest education certificate, employment history documents, marriage certificate and dependents' documents (if applicable), and a recent medical certificate. Our visa service in Thailand team provides a full document checklist at the start of each engagement.

Q: How far in advance should we plan for a new foreign hire in Thailand?

A: For a new foreign hire, we recommend starting the process at least six to ten weeks before the intended start date. The Non-Immigrant B visa applied for abroad typically takes five to fifteen working days after submission, and the work permit application in Thailand usually takes around seven to ten working days from complete filing. Add time for gathering corporate and personal documents, notarization, translation, and travel booking. If the employer is newly incorporated or does not yet meet the standard registered capital or employee-ratio thresholds, additional lead time is needed to arrange the company-side conditions before the work permit can be filed.

Q: Can you assist if our foreign employee is already in Thailand on another visa type?

A: Yes. Many foreign employees arrive in Thailand on a tourist visa, visa exemption, ED (education) visa, or dependent visa and then need to convert to a Non-Immigrant B visa for employment purposes. Our visa service in Bangkok team handles in-country conversions where permitted, which typically involves securing a letter from the prospective employer, filing with the Immigration Bureau, and then proceeding to the work permit application. In some cases the employee must travel to a Thai embassy in a neighboring country to collect the Non-Immigrant B visa before returning; we will advise on the most efficient route based on current immigration practice.

Q: Do your visa and work permit services cover dependents and family members?

A: Yes. Our visa and work permit services in Thailand cover dependent visas for spouses and children of foreign employees. This typically includes Non-Immigrant O dependent visas based on the primary applicant's Non-Immigrant B status, school enrollment documentation support for dependent children, and ongoing compliance such as 90-day reporting and re-entry permits for the whole family. For applicants eligible for the LTR visa, dependents can be included in a single family application covering spouse and up to four children under 20 years of age.
