does your wife have a permanent residence visa for the US?
Ok, I just read in another forum that you have been living in the Philipines with your wife for the last 18 months so I assume she doesn't have a US residence visa, which would have made things a lot easier for entry into DR.
If you use the search function you might find some information. Here is a link from an old post regarding Filipinos obtaining visas for DR.

Good luck.
