On December 12, TrucKhanh and I had a second wedding service in Las Vegas. This was not so much an attempt to "tie the knot" tighter, as it was, as TK's father put it, "register with the government". The VN government now makes it very difficult for a foreigner to marry a VN citizen, and so we went to Vegas, where the "paperwork" is much easier! We were thrilled that some of our friends and family made the long trip to be with us for this event! Thanks guys!
August 2010: Just a followup to the above statement.... As it turns out, there is still a lot of paperwork and red tape to register our Vegas wedding with the VN government. It might have been easier to get it done in VN after all!
