Just make sure you provide as much detail as possible about having the material means for staying in Thailand (savings account, having your parents guarantee they will sustain you etc etc). This is the most important part as they don’t you to become homeless or to work illegally in their country.
Participant anonim: 864 that’s totally bs. They don’t care if you are employed or not, but they care if you can sustain yourself financially for the period of your stay
Honestly, it was super easy for me. The biggest factors are the embassy you apply through and whether you go for a Workation or Thai Soft Power .HCMC is really strict these days, asking for tons of extra info. Meanwhile, I got mine approved in just four days in Jakarta. No extra documents, no hassle.
