Me and my friend have a one way ticket to Thailand and we plan on going to KPT school to learn Thai for 6/9 months. I have looked on the Embassy website but can’t get through on the phone for advice. Which VISA would we need to apply for to stay in Thailand whilst we wait the 6 weeks for KPT school to issue our ED VISA?
TLDR : Answer Summary
To stay in Thailand while waiting for your ED visa from KPT school, you can apply for a Tourist Visa which typically allows for a 60-day stay, extendable by another 30 days. Some users suggest that airlines may require proof of onward travel, especially if you have a one-way ticket, and remind that entering Thailand is at the discretion of immigration officers, hence an onward ticket may be necessary.
