I've been here 25 years and speak fluent thai. My source is directly from immigration. I take the time to talk with my local Immigration office when I have business there. Do you think a 3 month cooking class is really going to get you 5 years of entries into the kingdom? I know you are smarter than that.
if you stop meeting the soft power requirement of enrollment and attendance in courses they will revoke the visa. Alot of people think they will be able to come and go for 5 years when they sign up for a 3 or 6 month class and that is not the case. You have to continue to meet the requirements.
It has to match your passport exactly so manual entry is nesseary if automatic population of the form is wrong. And it's wrong alot so good thing you checked and noticed this. It's #1 reason people get application rejected. They don't proof read it before sending
The dtv is almost exactly 1 year since it started so all the people who are soft power applicants are going to face alot more scrutiny since many classes are generally only a few months long. There system does not tell them if the dtv was issued for workcation or soft power so everyone is lumped into the same group until it's declared. While the soft power is a 5 year visa it still can be revoked and entry denied If the holder cannot continue to prove enrollment and participation in a approved soft power program.
