1.  Documents that you should definitely have with you when traveling abroad include your passport, visa, and any other necessary identification such as a driver's license or birth certificate.
2.  Safety is always important while traveling, so it's essential to research local laws and customs in each country before you go.
3.  When crossing international borders, travelers may be asked to show proof of their identity, including a valid passport.
