I appreciate that the system works for the local people in Vietnam. They implemented the cost for its local people and different to the foreigners. I think its just a fair, like you mention about the friend you know for earning 2 dollars as a bartender. Without the system where do she live now, or even she has a comfortable to stay that the place she can afford. Fair system wise for the local tenants. If I did not expect that in Vietnam they will not allows foreigners in the building. Even its your boyfriend or girlfriend. I have a question, how about there married to other nationality? Still the same thing not allowed. maybe no right its foreigner too. But lets just respect their decisions and culture. My final comment: If travelling or an expat in other country much better do some research to the place you want to visit. Prices, places, rents, rules etc for transparency. And very important is to respect and follow the rules. Thanks for sharing!.
