What are the options for obtaining a tourist visa for Thailand if I have a US passport and can't get an appointment at the consulate?

If you're a US passport holder and can't get a tourist visa appointment at the Thai consulate, you have several options. You can enter Thailand under the visa exemption rule, which allows you to stay for 30 days upon arrival. This can be extended for an additional 30 days once you are in the country, for a fee of 1,900 baht. Alternatively, you can also opt for a Visa on Arrival at the Bangkok airport. Remember, after the maximum 60 days, you will need to leave the country before returning again.
