I think Shawn and ID are both partially right, but also partially wrong. The importance of family ties are important to ticas but I'm not so sure they're any more important to them than they are to many latinas in other countries. IMHO, there is much more to it than that. What I think really differentiates CR from its latin neighbors is that, for far more of its citizens, life is not so bad for them that they'd so easily give up those family ties for a "better" life in the US. Of course, that may be changing as the economy declines, CR's vaunted social safety net frays and crime increases. But life is still much better in CR than it is in neighboring countries like Colombia and Nicaragua, which are variously violent or economically depressed. Thats why you see so many more Colombianas and Nicas coming to the US than ticas but it is also why they migrate to CR as well.
As for what shawn describes, I'm sure he has run into a tica with a tale like that but I'm not so sure how representative that is. Perhaps it has something to do with which social class she comes out of and what her family background was like in CR. Maybe she really didn't have as much to give up by coming to the US or that much to go back to. And the fact that so many of us would want to leave the US for CR (beyond just the base appeal of cheap P4P) is all the more argument to support why ticas themselves want to stay in their own country.
My own spin on this issue is that if you want to find a latina for bringing back to the US your best odds are to look for nationalities OTHER than ticas. Just bear in mind that if and when she learns english and starts mixing with gringas, you'll probably wind up a wife that combines all the worst qualities of both types of women. OTOH, if you want to relocate to CR anyway then ticas have some endearing qualities that might make them good candidates (not the least of which is that there are so many of them in CR

) But even there your best bet might be to find some other nationality like a colombiana that is already living there. This way you may have the best of all worlds - a latina wife that stays a latina and life in a tropical paradise. YMMV
