Thanks Mike,
My question about the embassy validating the driver's licence refers to whether or not they will confirm for the DR government that it is legitimate thereby eliminating the need for having to start the residency procedure and obtaining a cedula prior to getting a Dominican Driver's licence. The US does not validate driver's licences so US citizens must go this route where many European countries will validate their driver's licences and therefor their countrymen can obtain a Dominican licence much faster and with far less paperwork and expense.
