However, for the DR, they just want to be sure you are who you say you are. You do have to return to your country of origin and after 9/11, things can get sticky if you don't have good, solid picture IDs on you.
Spend the bucks and get a passport, they can be expedited and you can have one in the time you have left.
However, bottom line:
No you do not need one. A good Birth Certificate and a couple of good Photo IDs are sufficient.
