Do I need to show an onward flight for a Multiple Entry 6-month visa to Thailand if I plan to extend it?

When applying for a Multiple Entry 6-month visa to Thailand, the requirement for showing an onward flight varies by country and consulate. Generally, proof of onward travel is recommended, typically within 60 days of entry. Some experiences indicate that while the consulate may request it during the application, it is less frequently checked upon arrival in Thailand. It's best to confirm the requirements with your specific consulate before applying.
