Yeah, this is a pretty big risk. I'm similarly married to an American and we have an American child. Other country seems to have screwed the family, though. Mine (India) offers a fairly indefinite visa called an Overseas Citizen of India. And my wife's other nationality (Taiwan) also permits foreign spouses to live there after some straightforward paperwork. So, in theory, we could live in either of these other places together. I suppose I will only know when push comes to shove.
