I agree with Berzin here, that is exactly what the majority of women do when they go to another country for a period of time. During the course of sitting there and having a beer with her, why don't you ask her why she came there in the first place, I am sure she will have some sort of line for you, but think logically (with your head, oh...never mind; that's what got you to asking the question in the first place

) but I digressed, if she is a poor Dominicana, and she has no family in the country, no visible means of support in the country, besides her obvious charms, why else would she be there?
I have not had the pleasure of visiting your beautiful country but have met a few people from there, and I am sure there are many reason why people visit there, but again why would
she be there if not for the reason that Berzin suggests??
I mean is she there on vacation enjoying your tourist spots?
Does she have any special skills...

.... that your country needs to further their economy?
If not..... again you have to be reasonable and understand why she is there, doesn't make her a bad person, but be honest with yourself (after all she has to eat and probably support her family, I actually applaud her for being so industrious).
