Thailand entry requirements: what to know before you travel
Thailand's entry rules combine visa type, passport nationality, TDAC registration, and proof at the border. Rules can shift quietly, so what worked on your last trip may not work on the next one. This guide summarises what our Bangkok team tells clients before they fly.
Whether you are landing for two weeks or planning a multi-year stay, start with the correct visa category and TDAC before you worry about hotels and itineraries. Wrong stamps are harder to fix in-country than before you fly.
Submit within 72 hours of each entry; required since May 2025
Eligible passports only; confirm the official list
COVID registration no longer applies
15 days for limited nationalities only
Obsolete requirements: not needed in 2026
If an old bookmark, forum post, or agent brochure mentions any of the following, it describes retired pandemic rules, not what you need today.
Thailand Pass
COVID registration portal discontinued in 2022.
Certificate of Entry (COE)
Pandemic embassy approval replaced by a normal visa or exemption plus TDAC.
Test & Go / Sandbox quarantine
SHA+ hotels and sealed flights were 2021–2022 entry schemes only.
Special Tourist Visa (STV) quarantine layers
STV COVID packages are obsolete. See DTV and current long-stay visas instead.
Step 1: Do you need a visa at all?
Three main paths exist for short visits:
Citizens of many countries enter without a visa for tourism. Current policy often allows 60 days, with a possible 30-day extension in Thailand, but government announcements have discussed shortening the initial period. Check your nationality on the official list before booking.
Limited nationalities can obtain a 15-day tourism stamp at eligible airports and land borders for 2,000 THB cash. See our Visa on Arrival guide.
If you are not exempt and not on the VOA list, apply for a tourist visa (TR) through a Thai embassy or the Thailand e-Visa portal. Typical stay: 60 days, extendable in country.
Step 2: Complete TDAC before arrival
Since 1 May 2025, all non-Thai nationals must submit the Thailand Digital Arrival Card online before entry by air, land, or sea. This applies whether you have a visa, use exemption, or use VOA.
- Submit up to 72 hours before arrival (Thailand time)
- Free on the official immigration site
- Required on every entry, including if you hold a long-term multiple-entry visa
We help travellers who want a second pair of eyes: TDAC service at TVC.
Step 3: Longer stays: pick the right visa
Tourism stamps run out quickly if you are relocating, working remotely, retiring, or joining family. Apply outside Thailand unless the specific visa allows in-country conversion.
Step 4: Documents to carry at the border
Immigration can ask for:
- ✓Passport valid 6+ months (minimum 30 days for VOA)
- ✓Return or onward ticket
- ✓Proof of accommodation
- ✓Proof of funds (amount varies by visa type)
- ✓Printed or digital visa approval for e-Visa
- ✓TDAC confirmation
Keep copies in email and cloud storage, not only in checked luggage.
Step 5: After you enter, stay compliant
Long-stay holders must track:
Overstaying even one day triggers 500 THB per day fines (capped) and can hurt future applications. See our visa overstay guide.
Most embassy applications are now online
Thailand's e-Visa system now covers embassies worldwide. Most applications are online with digital uploads, which means fewer in-person embassy visits. Processing times and document lists vary by post; allow several weeks.
- •Travelling with children: each child needs TDAC and appropriate entry permission
- •Medication: some prescriptions require prior approval, so carry doctor letters
- •Proof of vaccination: check current health entry notices
- •Land borders: stricter document checks than major airports; confirm your checkpoint accepts your visa type
Quick decision tree
Check visa exemption for your passport. If you qualify, confirm the allowed length and complete TDAC.
If you are not exempt, check VOA eligibility. If VOA applies, prepare 15-day documents and TDAC.
If VOA does not apply, apply for a tourist e-Visa or embassy visa and complete TDAC.
Staying 90+ days? Choose a long-term visa before you enter on the wrong stamp.
Entry planning workflow
Work through these named steps before you fly. They mirror what our Bangkok team checks on every pre-travel consultation.
Confirm visa category
Check exemption, VOA eligibility, or embassy visa requirement for your passport before booking flights. Wrong category at the border is harder to fix than pre-travel application.
Submit TDAC online
Complete Thailand Digital Arrival Card within 72 hours of landing on every entry. Long-stay visa holders are not exempt.
Prepare border documents
Carry passport validity proof, onward ticket, accommodation, funds evidence, e-Visa approval, and TDAC confirmation in carry-on.
Plan long-stay path early
If staying beyond tourism stamps, apply for DTV, retirement, marriage, LTR, or employment visa before entering on the wrong stamp.
Register compliance after arrival
Track TM30, 90-day reporting, re-entry permits, and extension deadlines from day one.
Air versus land entry checks
Major airports see high tourist volume and standardised e-Visa and TDAC checks. Land borders may apply extra scrutiny, shorter hours, and checkpoint-specific rules.
Standard at immigration counters
Same requirement; confirm you have mobile data
Routine for major airports
Varies by checkpoint; extra proof is possible
Most e-Visa and exemption
Some visas not accepted at all borders
Peak tourist season queues
Limited hours at smaller crossings
Extended planning notes
Rules, fees, and embassy practices change. Verify against official sources within two weeks of travel or submission. TVC guidance reflects Bangkok team experience as of June 2026 and is not a substitute for legal advice on your specific facts.
Long-stay holders should cross-link this topic with Thailand lifestyle guide for visa category fit, TM30, 90-day reporting, and cost-of-living context.
- Confirm official embassy or immigration source before paying non-refundable fees
- Photograph passport stamps and set calendar reminders before expiry
- Keep digital copies of refusal letters, extension approvals, and financial proof
- Plan re-entry permits before leaving on single-entry extensions
- Ask TVC for case-specific checklist rather than relying on forum advice
Planning milestones
Use this timeline alongside the workflow above. Dates shift by embassy workload and your document quality.
Confirm eligibility, assigned post, and document checklist on official portals.
Complete affidavits, translations, and legalisation in the order the checklist requires.
Submit application with cross-checked names, dates, and financial proof.
File TDAC, register address, and set 90-day reporting reminders before long-stay life begins.
Core document checklist
Most Thailand visa, property, and consultation cases ask for variations of these documents. Your TVC checklist may add category-specific items.
Passport biodata page
Must match every form field including middle names and spacing.
Passport photos
Recent, white background, per embassy specifications.
Financial proof
Bank statements or pension letters meeting category thresholds.
Supporting affidavits
Embassy or notarised documents when required for your nationality pair.
Compliance reminders for long-stay holders
Tourism advice forums often skip post-arrival duties. These reminders apply across most categories. Privilege and some LTR tiers simplify reporting but not TDAC or overstay rules.
- ✓Complete TDAC before every arrival at tdac.immigration.go.th
- ✓Ensure TM30 address registration within 24 hours of check-in
- ✓File 90-day reports on schedule for long-stay categories
- ✓Match daily activities to your visa stamp category
For TM30 detail see TM30 guide. For 90-day reporting see 90day.in.th.
Frequently asked questions
Q:Can I enter on visa exemption and convert to DTV inside Thailand?
A:Usually you must leave and apply from outside, or meet specific conversion criteria. Do not assume.
Q:Is travel insurance required?
A:Not always for entry, but retirement and some visa types require it; insurance is strongly recommended regardless.
Q:Do permanent residents need TDAC?
A:Yes, on every entry.
Q:Do children need their own TDAC?
A:Yes. Each traveller including minors needs a separate TDAC submission for every entry.
Q:Can I work remotely on visa exemption?
A:Tourism stamps are not work visas. Remote work for foreign employers exists in a grey zone but is not what exemption is for. Use DTV or another appropriate category if basing in Thailand.
Q:What if my TDAC submission fails?
A:Retry on the official immigration site. Do not fly without a confirmed submission if immigration is enforcing TDAC at your checkpoint.
Q:How much passport validity is required?
A:Six months beyond entry is standard for most routes. VOA may accept 30 days minimum but airlines often enforce six months.
Q:Are land borders stricter than airports?
A:Often yes. Some checkpoints reject certain visa types or demand extra proof. Confirm your route accepts your permission before travelling overland.
