Entry & Long-Stay Visas for Thailand

Whether you plan to visit Thailand for tourism, work, retirement, investment or family-based residency, securing the correct visa is fundamental. The Thai immigration and consular framework offers different classes of visas, each with specific conditions, documentation and ongoing obligations. At BASE Law Firm, we assist both individual and corporate clients in navigating the visa process, ensuring compliance and aligning stay status with your objectives.

Our service include:

Visa category assessment guidance
Eligibility review and documentation preparation
Embassy and immigration coordination
Visa extensions and status changes
Work-permit planning and compliance
Ongoing reporting and renewal support

Purpose-Based Visa Options

Thailand offers a range of visa categories depending on your intention:

Short-term visitor/tourist visas: For travel, leisure or short visits without permitted employment.
Non-Immigrant visas: For longer stays tied to business (Non-Immigrant B), investment (Non-Immigrant IM), marriage/long-term family stay (Non-Immigrant O), education (Non-Immigrant ED) and other specific activities.
Special & long-term residence visas: For retirees, affluent individuals, digital nomads or those holding investment credentials, enabling extended stays under defined conditions.

Key Requirements & Considerations

Purpose must match visa category: Your stated reason for entry and stay must correlate with the visa you apply for; working without proper authorisation can lead to serious consequences.
Documentary evidence: Includes passport validity, application forms, photographs, proof of travel/accommodation, financial capacity and purpose-specific documentation (e.g., business plan, marriage certificate, school enrolment).
Entry doesn’t equal automatic stay: Possessing a visa doesn’t guarantee entry, nor does entry guarantee permission to stay for the full period without compliance with conditions and immigration procedures.
Ongoing compliance: Some visa types require periodic reporting (e.g., 90-day address notification), re-entry permits, renewal and adherence to conditions (such as permitted activities).
Changing circumstances: If your situation changes (for example switching from tourist status to work, or from non-immigrant to retirement), timely legal advice is essential to manage transition and avoid violations.
