When foreign executives, specialists, or business owners prepare to work in Thailand, securing the appropriate preliminary documentation from the Department of Employment is a critical early step. The WP.32 form (commonly referred to as Tor Tor 32) serves as a formal application for pre-approval or endorsement, allowing Thai embassies and consulates abroad to issue the required Non-Immigrant "B" Visa, or supporting the issuance of a regular Work Permit upon arrival.
Navigating the statutory documentation required for a WP.32 application involves strict adherence to corporate threshold rules, registered capital verification, and Thai staff hiring ratios. TILA LEGAL provides legal advisory and document auditing services to help foreign investors and Thai corporate entities structure their WP.32 supporting document packages accurately before official submission.
Key Takeaways: WP.32 Supporting Documents
- Purpose: WP.32 acts as a pre-approval notification or supporting endorsement from the Department of Employment for foreign workers entering Thailand.
- Corporate Prerequisites: Requires verified statutory corporate capital (typically 2 million THB registered and paid-up capital per foreign employee) and compliance with the 4:1 Thai-to-foreign staff ratio, subject to specific regulatory exceptions.
- Document Stack: Involves corporate registration records, recent monthly tax filings (P.P.30), Social Security filings (S.P.S. 1-10), audited financial statements, and position justification letters.
- Role of Advisory: Independent legal review ensures consistency across statutory company filings and prevents submission delays caused by incomplete or conflicting documentation.
Who This Service Is For
Our WP.32 supporting document advisory service is structured for foreign businesses, investors, and Thai corporate entities that require thorough legal review before submitting applications to the Department of Employment:
- Foreign Investors & Executives: Key personnel preparing to relocate to Thailand who require official pre-approval documentation for consular Non-B visa processing.
- SMEs & Newly Registered Companies: Businesses in Thailand establishing their initial foreign employment headcount and requiring verification of statutory capital and staff ratios.
- Corporate HR & Legal Departments: In-house teams seeking external legal review of complex employment background files, statutory company books, or corporate position rationales.
- Representative & Regional Offices: Foreign corporate entities operating under specific regulatory frameworks with tailored document submission requirements.
Scope of Our WP.32 Supporting Document Services
TILA LEGAL assists clients by reviewing corporate readiness, auditing statutory documentation, and preparing the supporting written submittals required by Thai labor authorities. Our services include:
1. Corporate Compliance & Ratio Audit
We review your company’s current corporate profile, including the Certificate of Incorporation, List of Shareholders (BorOrBor 5), monthly Value Added Tax returns (P.P.30), and Social Security filings (S.P.S. 1-10), to verify that statutory requirements for foreign employment are fully met.
2. Document Preparation & Rationale Drafting
Labor authorities frequently require detailed explanations regarding why a foreign specialist or executive is required for the specific corporate role. We draft formal legal rationale letters detailing the specialized skills, operational necessity, and organizational structure supporting the WP.32 filing.
3. Consistency Verification Across Filings
Discrepancies between company registration objects, reported revenue in audited financial statements, and stated job descriptions are common causes for application rejection or requests for additional evidence. We ensure alignment across all official documents before submission.
Service Boundaries: TILA LEGAL provides legal advisory, document auditing, and formal document drafting. We do not offer guarantees of government approval, nor do we submit false or unverified corporate records. Final decision-making authority rests exclusively with the Department of Employment and relevant ministry officers.
Key Legal and Practical Considerations
Before initiating a WP.32 supporting document submission, corporate entities must evaluate several statutory and practical prerequisites under Thai labor regulations:
| Consideration Area | Statutory / Practical Requirement | Legal Impact on WP.32 |
|---|---|---|
| Registered Paid-Up Capital | Generally 2,000,000 THB per foreign employee (1,000,000 THB if married to a Thai national). | Must be fully paid up and reflected in audited financial statements or corporate bank confirmation letters. |
| Thai Staff Ratio | Standard rule requires 4 full-time Thai employees registered under Social Security per 1 foreign employee. | Verified against recent monthly S.P.S. 1-10 filings prior to issuing the endorsement. |
| Tax Compliance (P.P.30) | Active Value Added Tax (VAT) registration (P.P.20) and up-to-date monthly P.P.30 filings. | Inactive or non-compliant tax filings will lead to immediate requests for secondary inspection. |
| Physical Business Location | Verifiable commercial premises with official signage, operational workspace, and clear location mapping. | Authorities may inspect photos or conduct site visits to verify real commercial operations. |
Common Pitfalls in WP.32 Submissions
Delays in obtaining WP.32 endorsements typically stem from administrative oversights rather than statutory non-eligibility. Common issues include:
- Expired Corporate Documents: Presenting company certificates (Affidavit/DBD) issued more than 30 or 60 days prior to filing.
- Inconsistent Job Titles: Discrepancies between the position stated in the board resolution, the WP.32 form, and the official rationale letter.
- Premature Filings: Applying prior to completing full capital registration or prior to submitting initial monthly Social Security returns for Thai staff.
- Insufficient Educational/Experience Proof: Failing to provide certified translation or legalisation of foreign professional credentials where required by specific regulatory categories.

Frequently Asked Questions
What is the primary difference between a WP.32 letter and a Work Permit?
A WP.32 (Tor Tor 32) is a pre-approval notification or preliminary approval letter issued by the Department of Employment. It serves as evidence for Thai embassies abroad to issue a Non-Immigrant "B" Visa. A Work Permit is the final official digital or physical booklet issued after the applicant arrives in Thailand and completes full biometric and employment registration.
How long are supporting documents valid for WP.32 submission?
Official corporate records issued by the Department of Business Development (DBD), such as the Company Affidavit and Shareholder List (BorOrBor 5), generally must be dated within 30 to 60 days of submission depending on local Department of Employment office guidelines.
Can a company apply for WP.32 before the foreign national enters Thailand?
Yes. The core function of the WP.32 pre-approval process is to allow the employer in Thailand to submit supporting documents while the prospective foreign employee is still abroad, enabling them to secure the proper Non-Immigrant "B" visa prior to arrival.
What happens if the company does not meet the 4:1 Thai staff ratio?
Unless the entity qualifies under specific statutory exemptions such as Board of Investment (BOI) promotion, foreign government treaties, or representative office rules, applications that fail to meet the mandatory staff ratio will be rejected. Our legal team reviews entity eligibility prior to drafting documents to identify applicable frameworks.
