Sorry it will have to come down this way. It is what it is. The thing I'm not exactly sure if I understand correctly, you mean even when we have enough money to bribe all the way to make it through with a Cambodia wedding certificate, you still can't get a K-visa?
My only concern now is, whether is it possible? I remember you mentioned many Chinese fat asses has a Khmer waifu there without worrying if they get kicked out.
The K-Visa is not possible, the Ministry isn't educated on their own laws, and just as I suspected it is only available for those with some Khmer DNA. I did discover there is a 3-year visa, but it's only available to Korean, Japanese, and Chinese nationals, bummer. It looks like I will only ever have a one-year solution for the foreseeable future, but at least it looks like I can renew my visa in person at the Immigration office for far cheaper than visa agent costs, and I won't need a work permit to do this.
