You will need to present proof of citizenship. This may be in the form of a passport or, in many cases, you can present an original raised seal birth certificate and a photo identification. Your photo identification will also be required to board your flights. Depending on your itinerary, you may also require a visa or other paperwork.
The cruise line will provide you with detailed information about entry and document requirements. However, it is your responsibility to check with local immigration offices and/or respective embassies or consulates to determine specific document requirements. No refund will be issued if a passenger is denied boarding by local immigration officials due to lack of proper documents.
