Wondering if anyone has been in a similar situation.

Currently working in Thailand with permit and visa, however my contract will end this month and will not be renewed.

My thoughts are to go freelance and move services online.

The DTV could be a great option for this. I'd leave the country once visa expires and apply out of country. However, I'm unsure how to show a portfolio of work with a new business.

What is currently being accepted as proof of work/portfolio documents?

Is there a requirement to show company registration or income from services?
