What documents do I need for a Thailand visit B visa?

So that’s that 😊

Did you try to google this question ?? I did and found more then enough information on the first click after pressing enter :)

Whatever paperwork your company provides to you to show that you have a job offer and that they are applying for your work permit.

Most companies in Thailand either cannot or will not supply the paperwork required to do this inside of Thailand because it requires a truly massive amount of paperwork. Most companies will send their prospective employees out of Thailand to apply at a Thai embassy, where much less paperwork is required. Your employer should know what process works for them and tell you which one to do.
