Introduction: Know Before You Go
Planning to travel to the United States of America in 2025? Whether you’re visiting for business, leisure, education, or family, there’s one thing all international travellers must go through: TSA security screening.

What is the TSA?
The Transportation Security Administration (TSA) is a division of the U.S. Department of Homeland Security. It was created after the 9/11 attacks to protect air travel and ensure security in all U.S. airports.
TSA agents are stationed at every security checkpoint in all major U.S. airports and are responsible for:
-
Passenger screening
-
Baggage inspection
-
Identifying prohibited items
-
Detecting security threats
As an international traveller, you will go through TSA screening even if you’ve already cleared immigration and customs.
Documents Required for TSA Clearance
While the TSA does not handle immigration, you will still need the following to pass through airport security:
✅ Valid Passport
Must be current and match the name on your ticket.
✅ Valid U.S. Visa or ESTA
Depending on your country of origin, you must have an approved visa or ESTA (Electronic System for Travel Authorization) under the Visa Waiver Program.
✅ Boarding Pass
Printed or digital—must be presented at TSA screening.
💡 Tip: Keep these documents handy in your carry-on, not in your checked luggage.
TSA PreCheck vs Regular Screening
✅ TSA PreCheck
-
Available for U.S. citizens and legal residents
-
Offers faster screening, no need to remove shoes/laptops
-
NOT available to most international visitors
🛂 International Travelers
You will use the standard TSA security lanes. Some foreign airlines may be part of Global Entry or International Trusted Traveler Programs, but you still must undergo full TSA screening.
