@ossobucotemp,
Yes, you should date this girl. Why not? If you want to have a sexual relationship with her, and she does too, why wouldn't you?
This woman is a foreigner and a student. She isn't mentally challenged. She is probably more intelligent, independent and adventurous than most. There is no reason that this young woman can't choose for herself whether she wants to have sex with you.
I think the other posts on this thread are operating on the old-fashioned assumption that women don't like to have sex. If you pursue this relationship and this woman wants a sexual relationship with you, she will respond positively. If she says no, then you walk away.
You are two consenting adults. If both of you want to have sex, then you should have sex without seeking the approval or worrying about the judgement of random people on the internet.
I would say "go for it"! Life is for living and you and she might both end up with a very enjoyable experience.
