1. Make sure you have a valid passport and visa before leaving the US.
2. Research your destination cities, including their culture, attractions, and safety precautions.
3. Book your flights and accommodations in advance if possible.
4. Consider taking an international driver's license with you for added convenience when exploring the country.
5. Bring cash and credit cards from home so that you can use them abroad.
6. Pack light, but bring items such as sunscreen, sunglasses, comfortable shoes, and clothing appropriate for the climate of the destination.
