Additional Details : Basically I would like to stay in Thailand and do some work (research on my own) and study online to gain new skills without getting paid. Which visa I could get. I was under the impression that DTV is a tourist visa for long term.

Original post:

I'm applying for DTV from Toronto. I'm not working since April. I plan to select "workcation" under purpose of visit and wonder what option I should choose in occupation category which has options like Unemployed, freelance, remote. I was hoping I would be considered under foreign talent category since I have a PhD in Science and past experience with biotechnology. I will be doing some independent research from Thailand. I have sufficient bank balance. I wonder are there documents I should attach other than my Resume, PhD Certificate. Would that be enough ? is being unemployed going to be a problem. Thanks !
