Trying to figure out what visa I need to get. Please advise....

I'm accompanying my 16 yo daughter to Thailand for 90 days. She will have a non imm b visa for working. We hope to stay an additional 8 days after her work is done to travel. I "think" her work visa can be extended without issue?. But I'm the issue with my Visa.

One embassy said I should get non imm O because I'm her chaperone but when I look at what that Visa says it's about it doesn't say anything about what I needed for but I like that it is for 90 days and I'm assuming can be extended if my daughter needs to stay longer. Can I then extend this so we can travel?

The TR Visa is good for 60 days plus 30. But then do I have to leave or can it be extended again? This would be my easiest option if it can extend again.

The STV seems like it might work but asks for so much stuff and I really only want 8 more days not 180 so might be overkill in work getting it.

Any thoughts, the embassy gives me different answers depending on what day it is so I'm unclear. Thank you!

Hello, any information much appreciated...

I have non imm b visa and my husband got a non imm o visa (based on his marriage to me and I have a job in Thailand). He will do his extension next week that will allow him to stay for the length of my work contract hopefully. Does anyone know if he'll be required to leave the country every 90 days or if he can just do the 90 day report at the local immigration the same as me? I've heard different stories.....

Thanks for any info.
