You're best bet is to forget this guy.
Not to worry though, there are literally thousands of Dominican guys in the States who would love to have a gringa as a girlfriend, and many speak English to boot. You best bet is to communicate with the via the social networking website. A real bonus is that they won't be after you at the very least for a residence card in gringolandia (wherever ithat may be), as they already have one if they aren't already a citizen of wherever they live.
I in fact have two family members on the wife's side that live in NY (maybe illegally ?

), that are doing their best to find a gringa girlfriend, but alas to no avail. I keep telling their family to tell them to learn English, but it is easier said to done. Nonetheless, one of them left a promising medical career here in the DR to sweep floors in NY and after three or four years I doubt he'll have saved US10k. The point is I know he's there because of all of the gringas, hehe.
