What type of visa should I apply for my 2-3 month stay in Thailand?

For a stay of 2-3 months in Thailand, you have a couple of options. The Single Entry Tourist Visa allows for a 60-day stay, which can be extended for an additional 30 days. Alternatively, if you're an American citizen, you can enter Thailand without a visa and receive a 30-day visa exemption on arrival, which can also be extended by 30 days for a fee. It's important to apply for the appropriate visa before departing, based on your nationality and plans.
