Hi guys, one of my friends is coming to Thailand with some questions and info I hadn't heard about.

He is coming from Romania by plane in about a week. He says he will get a visa-on-arrival for 15 days? (I thought it was 45 or 30 days but they keep changing it, it seems.) And he also said the visa-on-arrival is non-extendable. Is that right?

He plans on staying in Thailand for around 40 days, and he is wondering what would happen if he overstayed his visa-on-arrival. Besides the fine when leaving the country, would he still be able to fly around from city to city, or would he get stopped? He is thinking of eating the fine, no sweat, and traveling as per usual.

What do you think? Thanks for the help!
