1. Introduction

Many first-time travelers believe this:

“If I have a passport and visa, I can enter for sure.”

In reality, this is not always true.

In ASEAN countries, immigration officers have the right to:

• Ask questions
• Check your documents
• Deny entry if they believe you do not meet entry conditions

Being denied entry does not always mean you did something illegal. Sometimes it is due to missing documents or unclear travel plans.

2. What Does “Denied Entry” Mean?

Denied entry means:

• You arrive at the airport or border
• Immigration officers do not allow you to enter the country
• You are sent back to where you came from (or another country)

In simple words:

• You are not allowed to pass immigration
• You do not officially enter the country
