How do I present my E-Visa at Thai immigration upon arrival?

When arriving in Thailand with a 60/90 day E-Visa, you should present your printed copy along with your passport at immigration. It's advisable to ensure you receive the correct 60-day stamp instead of a 30-day stamp after your passport has been processed. For extensions at immigration offices, a printed copy of the E-Visa is often required as showing it digitally may not be acceptable.
