I don't have to take a flight to get to the bathroom. 2 trips to Bangkok plus a hotel room and time wasted is more expensive than mailing your passport and application to an agent in Bangkok who can do it for you.
He's not going to have a problem because he hasn't done anything wrong. But in the case of someone who has been banned for a long overstay for instance a new passport won't help.
let's be absolutely clear about this from someone who has lived here for 25 years. You can enter Thailand as a tourist on a 45 day exempt entry by just showing your passport when you walk through immigration. You don't apply for anything online. You don't have to prove where you're staying. Technically they could ask you to show that you have 20,000 Baht and an onward plane ticket back to the States but personally that has never happened to me in all these years. I think you can be confident from what you have heard here that you just need to get on a plane and get here. Enough already!
seriously? This sounds too complicated for you. I think it would be better if you stayed in the US and took a vacation there. I'm wondering how many people it's going to take to convince you that you just walk in with your passport and get stamped in for 45 days. 😃
