I think I can just relate to the OP. He doesn't delve into it much but I'll explain my rationale for the continued asked question...why not get a viet american wife? For me, I don't live an an area w/ a lot of viet women or viets in general. The ones that are here, I dont know any of them. Most of them are way to young or married already if they were able to immigrate here. If not well quite frankly they are 'american'. Thats not meant to be offensive just honest. Hell my sisters are american. I am too.

I started to see vietnam enter more mainstream media and saw the country for its beauty and intruige. I passed multiple offers from my friend to go with his family (cause honestly i thought weird to go back to homeland w/ someone elses family vs my own, particularly for my first time) I had always waited my entire life for my family to go back on one epic trip home, but my sisters had kids and it never happened and one day i realize if i waited for someone to send me the itinerary...it would NEVER happen. So I said F it and I DID something about it. I planned it. I went. Whomever wanted to go w/ me could. I told my parents...I'm going on VACATION, this was not a pilgramage home. I did not tell anyone I was coming, until I was already there. I went 3 wks and said 2 weeks I'm travelling not chilling at grandma's all day. It was awesome. Best decision I ever made. One day I realize as more and more time went on, I couldn't udnerstand my mom as well anymore, I was working my ass off and she called and I literally couldnt recall the conversation. Thats not good. As the baby boy I felt a bit disenfranchised by it all. I went online looked up some syntax and a few rules, started using subtitles, and taught myslef good enough to communicate w/ cousins I met and stuff and having a small family here its nice to connect to a bigger family.

As for the wife thing, I just wanted to find someone that shared some of the values and expectations I grew up with. Can you find that here in the US? Sure. For instance I forsee having to help my folks as they grow older. My viet wife, has a greater expectation that I should do that than myself. Viet american girls here grew up here, they dont necessarily share the same values anymore. Just like Saigon, the western influences have really creeped into VN. I been back several times now and its changed so much just in the past few years. When I think how much has changed from my childhoon here, to think what its been like just in the past few years there is mind boggling. The western influences are sort of insidious. Its not all bad, but certainly a lot of the 'little things'. Do people want to marry up? sure as hell they do thats evolution and just plain smart. Does that mean looks, financial, values? Thats up to whomever. If you goto visajourney.com, you'll find people met playing everquest that still play and still married. Who cares. I think finding a wife on Tinder seems more discomforting. Are asian girls bitchy? uh, thats pretty broad generalization but they do have a mothering/nurtering thing that never turns off so its more like nagging than bitchy. IMO. Its the insessant reminding that is unnecessary that gets annoying but its not bitchy. My wife and I still have a language barrier, but honestly as frustrating as it is. I WELCOME it. We have to choose our words. We have to take time to understand each other. Things I think all my married american friends have demonstrated doesnt happen much anymore, untill they are divorced and have to watch what they say because of the lawyers. We had to communicate 1/2 way across the planet. Thats a pretty big committment in my book, and epic LD relationship that we made work, so I think can give a good foundation moving forward. All these years I waited I did just sit, I observed things I didn't like what I didnt want in a women, what I promised Id do or wouldn't do...'when i got married'
Don't get me wrong its a lot of work. I feel like its another 'job' shes visiting and not home this wk. I literally feel like I'm on staycation. To the OP's question...I dont think the law enforcement thing is a big deal at all. Focus on the girl. If you have family trust them for networking but yes be cognizant of the tangential stuff of a the green card pipeline. I got introduced from life long friends. I trust. Sure they dont really know them either a hemisphere away, but that gave me sense of relief. I met her entire family and they were all genuine and awesome. That helped solidify for me I chose well.

Familial expectations going forward. Her expectations and adjustment to life here. What your expectations are and what YOU are willing to do. Would you be willing to support her fam, there and here? How many? What limits? Establish them. Would you have issues sponsoring her folks/family here? If you haven't met any / her... Dont rush. Don't get in over your head.
