I'm kicking around the idea to take my wife, who is Dominican and only has a DR passport......and my daughter who has a USA passport to Peru. My concern is that when we go to fly out of the DR that there may be something I am not aware of...a reason that they would prevent my wife from leaving. My understanding is that DR citizens can fly to Peru using a DR Passport. No visa required. Is there any other document that may be required. Any other reasons they my stop her.
