I think not many read your word here, but let's see how it playout. I understand why they prefer to be in the US to live like a refugee, just like any other Asian people thinking migrating to the US will magically solve all their problems facing a third world country. And I get why you rather live freely in Cambodia, than having to work 5 jobs a day and half of the wage needed to be taxed away just to have enough to rent a parking lot at the entrance of animal shelter.
Pardon the negative energy, but the world is seriously fucked up at this stage.
