Before You Go to Thailand: 2026 Pre-Trip Checklist

In short: Before you go to Thailand, line up a passport valid for at least 6 months after arrival with a blank page, the free TDAC card filled in up to 3 days before arrival, a return or onward ticket, accommodation details and proof of funds. Turkish passport holders don’t need a visa, but the visa-free stay is limited to 30 days.

1. Check Your Passport

Your passport must be valid for at least 6 months after your arrival date and have at least one blank page. Airlines may check this before boarding, and you can be refused if it doesn’t meet the rule.

2. Plan Your Length of Stay

For Turkish passport holders the visa-free stay is 30 days since 15 September 2026. If you plan to stay longer:

• You can extend the visa-free stay once by 30 days at an immigration office (1,900 THB). Details: Do Turkish citizens need a visa for Thailand?
• If you work remotely, there’s the DTV visa.
• If you’ll study, there’s the ED visa.
• To see them side by side: DTV vs ED vs tourist visa.

Overstaying costs 500 THB per day and risks an entry ban, so fix your return date early.

3. Fill In the TDAC

The Thailand Digital Arrival Card (TDAC) has been mandatory for all foreign nationals since 1 May 2025. You complete it online up to 3 days before arrival; it’s free and replaced the paper TM6 form. Use only the official site: tdac.immigration.go.th.

4. Keep What Immigration May Ask For

The immigration officer may ask for the following. They may not check every time, but you should be able to show them:

If you haven’t bought the ticket yet, use my flight price analysis tool to compare months on your route.

5. Customs and Prohibited Items

Declare anything that may be prohibited or subject to duty. More than 200 cigarettes per person is illegal; the excess may be confiscated and fined at 10 times its value. E-cigarettes and vapes are banned outright, so keep them out of your luggage. I put the rules on what’s illegal in one place: What is illegal in Thailand.

6. Health

If you arrive from a country with a risk of yellow fever transmission, you need a vaccination certificate. For other vaccine advice, check official travel-health sources in your country. Travel insurance doesn’t appear among the official entry requirements; buying it is your call.

7. Prepare for Scams

I described what you may meet right after leaving the airport in my tourist traps guide. For a plan of your first days, see your first 7 days in Thailand.

Sources and Limits

The passport validity, TDAC, funds threshold, cigarette limit and yellow fever requirement come from the UK Foreign Office’s entry requirements page; the TDAC being free and the accommodation requirement come from other published sources. Rules can change. This page was last updated on 4 November 2026.
