As an update, I have been speaking to the Dominican consulate in the States (MIA and DC), and apparently, as of 9/1/09, the Consulate's translation of these documents is no longer legal. According to the Consulate, the DR is now part of the HAC Convention, so their translations are no longer accepted.
I passed this information on to my onsite coordinator, who of course, this was news too, but I called the Consulate back and spoke to the person who actually does the translations. I am obviously still going to have them done anyway, but this has been very confusing!!! Ugh!
