When flying internationally, you MUST bring your ORIGINAL aircraft and crew documents:

Airworthiness Certificate
Registration Certificate (permanent or Fly-Wire, no pink copies)
Radio Station License
Aircraft Insurance policy stating coverage for the geographic territiores of over-flight and destination(s)
Airman Certificate (Pilot License)
Medical Certificate
Restricted Radio Operator Permit

When the aircraft is not registered in your name, it is also recommended to bring a letter stating that the owner authorizes you to fly the airplane to the destination(s) on a PRIVATE flight and that the people on boards are friends/relatives of the onwer.

It is also a good idea to bring plenty of copies of the above.
