If you're to be paid 60k per month and have all your costs covered as well, you really are worrying about nothing. Obviously if you have a weakness for expensive women or a penchant for Fabergé Eggs, your salary won't go far.
NW, congratulations on not being an ethnocentric American (oxymoron?)! Ah Vietnamese women... So beautiful, so female, so... caring.... But, they can be the opposite as well, greedy, materialistic conniving, Prevaricator extraordinaire! You must understand her upbringing - Sounds like her parents had money, so her education went like this - every night after school, kids with enough money go to their teacher's house for paid "tutoring," along with their classmates who can afford it. in most every class, too. These children "score well" in that teacher's class tests, poorer kids must cheat off of them if they are to succeed - and most do not succeed. Nearly ZERO learning is ever accomplished here. Next, daddy likely sent her to private schools, English schools, etc. because public education doesn't really exist here. unless she is an unusual case, she knows nothing (ZERO) of world history, science, politics, or in any way know about another culture - including Cambodians - their neighbors. Knowing her family can help you decide about her - so a trip to meet her family is a must. If they are a lying, greedy bunch - lookout for the daughter. Please understand, the average Vietnamese will lie about anything and everything (this is a fact, not a judgment) - either to make face - or to get what they want ($$$). I live here. It is still hard to believe... Usually, Viet Kieu who are moi qua (new to US) focus on making money for themselves and their family back home. If she constantly talks to you about helping the family back home - in an almost desperate way, you are a wallet, not a suitor. RUN despite her cuteness. If her parent's sent her money to buy a house - then they are not typical average Vietnamese. SO the family may be government official of some type, or war "heros" Very likely... Vietnamese children in VN, have the most unusual upbringing compared to Americans, The typical child here is never corrected, they are fed on foot, with mama chasing the playing child with a spoon. Average kids here are never told to be quiet, be still, be nice, and are never forced to do anything the little darlings don't want to do. ADHD is rampant here - there is little parental influence on the child's behavior during rearing - because they are called "children" until they die. Americans encourage kids to act their age - Vietnamese treat their kids like - kids - never expecting anything of them because they are kids. And the teachers and parents further promote such hands-off child rearing "strategies." Vietnamese kids NEVER experience the consequences of their bad behavior - they are shielded from it. Consequently, most kids are about 4 years behind the US peers in maturity level. Kids are sequestered at home in HCMC for the first 5 years of their life - and then are frightened of everything a 6 y/o - even music scares them if its "scary." ??? Viet Kieu are totally different in my experience, the kids behave very well. Watch out for girls from the North - they are more like American girls in a bad way. Hue girls are cute but can be greedy, small minded, and xenophobic. Lying is normal there for most. And watch out for southern girls here - they can be enormously greedy. Finally, she is from a different culture. There are differences and one important one is an aversion to overt public displays of affection either doing are talking. So, it is what she does in private that I would focus on - don't read her behavior through your American eyes. However, there is one caveat to remember. If her behavior is rude or offensive in your culture - then its also offensive in her culture. Run away. Vietnamese worry by nature, and make up problems where non previously existed. She very well could be worrying over your schedule. IS she Buddhist or Catholic? Catholics here are like the 1960 Catholics in the US. E.G. "a gay person's soul is wasted." they say - and so on. Make sure she isn't overtly racist/prejudice. Women here with Anglo men many times want to marry for a green card no matter what she says or does. After two years, that green card arrives, they leave - and get to stay in the US because of you. You don't need to worry about this - But, if she is materialistic in the least, always talks about money - always - run - there are plenty of Vietnamese women that are good decent and beautiful wives. If you are careful and have a little luck,you will find a keeper - If you do you'll never ever consider a Western woman again - I know. (sorry girls).
