DTV done in Korea (6 weeks!)
Some people here thought it was impossible to do in Korea as a tourist but it was not true. I've emailed them before applying and a tourist stamp is good enough for them.
Applied online as digital nomad. They asked:
* Only 3 months of bank statements
* Full employment contract
* CV
* Tourist Stamp in Passport
* Certificate of Employment (letter from a manager)
* Proof of accommodation (Airbnb in my case)
Big con - the amount of time it took to process the application the whole 6 weeks. And 4 weeks is the minimum, no special cases. I also did an email follow up every week just in case. It was a hassle in the end and I'd rather have done it in Laos or Vietnam in a much shorter time.
But if you want to experience Korea and also do a DTV just make sure you go there for 2 months for the lengthy visa processing.
