no I did not use a VPN, I live in Canada and I applied in Canada, but I could’ve been in Vietnam or Cambodia or Taiwan or China, as long as I have an address in Canada I could’ve applied anywhere in the world
I don’t think they ask that, they certainly didn’t with me, they asked for my address, if you’re staying in a hotel in Vietnam, that is your address, why would they ask for a visa stamp? 
Anonymous participant I tried for four days to make them understand why I was a remote worker, which I definitely am, I provided every document I could think of, and that they asked for, they told me to write a letter explaining my business activities, because I own my own business,I wrote them two different letters, in the end they said you should change your category to soft power activities, only then was I approved
exactly, I applied under remote worker and was denied, not sure why though as I am a remote worker, then they allowed me to change categories to "soft power activities", I got a letter from my Thai dentist and was approved the next day, then my wife the day after that, very easy process
My application took two days once I got the right documents to the consulate in Vancouver, then I applied for my wife, and that took one day, something is definitely wrong with your application, you can always phone them, at least the Consulate Vancouver accepts phone calls, and actually answers the phone and talks to you without any difficulty at all, one time they even called me, they have been so easy to deal with 
yes it took a little while because I applied under the wrong category, the consulate in Vancouver was wonderful, they even called me up and helped me and changed my category to soft power, applying online this way, easier than going to a consulate or embassy
