Single-Entry vs. Multiple-Entry Comparison
Common Questions About the Thailand 3-Month Visa
1. Can I apply online?
Yes. Some Thai embassies and consulates accept e-visa applications, but others still require in-person submission.
2. Can I leave and re-enter Thailand during the visa period?
Only multiple-entry visa holders can re-enter without reapplying. Single-entry holders must apply for a new visa after departure.
3. What happens if I overstay my visa?
Overstaying results in fines (THB 500 per day) and can lead to blacklisting or deportation. Always extend your stay before expiry.
4. Can I work on a tourist visa?
No. Employment requires a Non-Immigrant B visa and a valid work permit.
5. How long does processing take?
Processing typically takes 3–5 business days, though timelines vary by embassy.
Tips for a Smooth Application
- Verify all document requirements with your local Thai embassy.
- Keep digital and physical copies of submitted materials.
- Apply 2–3 weeks before your travel date to avoid delays.
- For complex cases (dual citizenship, business travel, etc.), consult a licensed visa specialist.
Health and Insurance Requirements
Some visa categories—particularly longer non-immigrant visas—require health insurance coverage of at least USD 50,000 in Thailand.
Even if not mandatory, comprehensive travel insurance is strongly recommended.
Common Mistakes to Avoid
- Submitting incomplete or inconsistent paperwork
- Overstaying your visa or missing renewal deadlines
- Applying for the wrong visa category
