A complete overview of Thailand Customs and Immigration requirements for travelers arriving at Suvarnabhumi Airport and other international entry points.

Understanding Thailand Customs and Immigration rules before you travel is essential for a smooth arrival. This guide explains how Thailand Customs and Immigration procedures work in 2025, including passport checks, TDAC submission, cash requirements, visas, and customs inspections at airports and land borders.

🚀 At a Glance – What You Must Prepare

Before departure, make sure you have:

• ✅ Passport valid at least 6 months beyond arrival
• ✅ Thailand Digital Arrival Card (TDAC) submitted online
• ✅ Proof of onward travel (flight or exit plan)
• ✅ Cash funds available (important – see below)
• ✅ Visa (if your nationality is not visa‑free or you plan a long stay)

💡 Tip: Save digital and paper copies of all documents.

🧑‍✈️ Passport & Entry Requirements

To enter Thailand, all foreign travelers must:

• Hold a passport valid for 6 months or more from the date of arrival
• Complete the Thailand Digital Arrival Card (TDAC) online

Thailand Digital Arrival Card (TDAC)

• Mandatory for all foreign travelers
• Replaced the paper arrival card in May 2025
• Required for air, land, and sea arrivals
• Must be submitted within 72 hours (3 days) before arrival

⚠️ Failure to submit the TDAC may result in delays at immigration.

💰 Proof of Funds – Cash Requirement (Important)

Thai immigration regulations allow officers to request proof of sufficient funds:

• 20,000 THB per person
• 40,000 THB per family

This amount is intended to demonstrate that you can support yourself during your stay.

Important details travelers should know:

• Funds are officially required in cash (Thai Baht or equivalent foreign currency)
• Enforcement is not always consistent, but checks do happen
• Officers are more likely to ask if:
  • You stay frequently or long‑term in Thailand
  • Your travel plans are unclear
  • You have no onward ticket

❌ Bank statements, credit cards, Wise or Revolut apps are NOT guaranteed to be accepted if the rule is strictly applied.

✅ Best practice: Carry at least part of the required amount in cash to avoid problems.

🛂 Visa & Length of Stay

Visa‑free entry

• Many nationalities qualify for visa‑free tourist entry (often up to 60 days under current rules)
