does a us citizen need a passport to travel to jamaica
Since 2008 all US citizens MUST have a US passport to be allowed to enter the United States. If your aunt travelled to Jamaica with just her US naturalisation certificate, she would not be able to board her plane back to the US. She would have to come to the Embassy to apply for a passport in order to return home. Issuing a new passport takes at least a week, so this could extend her holiday much longer than she had planned. The good news is that she can apply for a US passport before she leaves the United States.
