Travel requirements refer to the necessary documents and conditions travelers must meet before visiting a specific destination. These often include a valid passport, a visa, and proof of onward travel. Additionally, some countries may require travelers to show evidence of vaccinations or health insurance. Travelers should also be aware of any local laws and customs that may affect their visit. It's essential to check the latest information from official sources, such as government websites or the International Air Transport Association (IATA), to ensure compliance with all regulations before departure.
