Depends where you apply on the length of approval. It took me one day in Taipei, it can take 4 days in Manilla, Jakarta or one month in Paris. Same for flights and accommodation, many embassies do not require an actual booking, intended flight and accommodation is ok. Ideally you should stay until approved but there are some who have arrived and then switched to the DTV via a border run.
Anonymous participant IF you want to get the 5 year DTV you can get it via the Soft power option via a course such as Muay Thai , cooking or medical treatment. The other option is to omit the one month remote working clause.
Anonymous participant My remote work policy covers the 5 years of the DTV. If you can only work one month per year remotely, i would avoid including that in your application as you will likely get A METV - six month multi entry visa instead of the DTV.
Also inc contract of employment, letter from HR detailing your position, length of employment with the company. I included a remote work policy in my application in Taipei,
Vietnam does not have a 500k seasoning requirement, the latest 500K balance plus 3- 6 months of statements will be fine. What do you mean by business case request? describing your business ?
