It depends on where you meet them. The best place is in the Latin clubs. Speaking Spanish also helps.
Even me who has never stepped foot in the US knows Miami has plenty of latinas. Did the OP bump his head?
Miami, Orlando, Tampa/St. Petersburg, Jacksonville, Florida, Texas, California, New York, New Jersey, New England...Latinas are everywhere.
I do not know the odds. It is all up to him and how he carries himself. They will pick up on that. If he speaks Spanish and likes to dance, he's in there like swimwear.
I don't know if the OP was a troll or just stupid, but the 5 1/2 year old thread was bumped by a troll.
