Question. I’m currently in the States finishing up my application for a Non-Immigrant O-A Long Stay Visa, (retirement visa) and one of the activities I plan on participating in while living in Thailand is volunteering. Not exchanging work for housing/food, but plain old volunteering. I have read that to volunteer legally you need an O Visa. Will my O-A visa suffice or will there be some other TiT hoop to jump through? Thanks.
