When planning a trip to the US, be it for a holiday or business purposes, every traveler who is not a US-citizen should make timely arrangements to receive authorization for entering the country. If you are a citizen of one of the 36 countries participating in the Visa Waiver Program, you will not need a visum. Citizens from all other countries will have to apply for a visum.
