I was just rejected in Cambodia. No reason, no additional requests for documents. I applied through soft power Thai botany course, had the money deposited 1 week before and 3 months of bank statements. I noticed my hostel told me the wrong city for the current address. This might be the reason but I’ll never know. Hope to have better luck elsewhere.
The soft power organization told me their agency mentioned Cambodia isn’t granting any Chinese this visa. My middle name is Chinese but I’m Canadian. Mystery…
