I don't see why it can't work. One would have to be very open to a lot of changes in life. Like moving or having someone else move with them who has different outlooks on life and the world around them. If one isn't used to changes and isn't willing to adapt then it probably won't work as well, but even then one can always try. Although both sides would need to compromise and try to makes things work regardless of anything. I No one ever knows how something like "marriage across nations" would work unless they experience it first hand.
