A Visa Waiver allows citizens of certain countries to travel to another country without needing a visa for short stays, typically for tourism or business. This program simplifies travel by reducing paperwork and processing times, making it easier for visitors to enter the host country. Countries participating in the Visa Waiver Program must meet specific security and immigration standards. Travelers usually need to have a valid passport and may be required to complete an online application before their trip. This system promotes international tourism and strengthens diplomatic relations between participating nations.
