Travellers from Croatia will not require a visa to travel to the United States in the near future. According to the US government, Croatia will join the countries whose people do not require a visa to enter the country. This is being done as a sign of closer economic and security ties. The United States has a Visa Waiver Program in place for citizens of certain countries.
According to the Visa Waiver Program, citizens of these 40 countries (now including Croatia), will be able to travel to the United States for a period of up to 90 days for tourism or business without a visa. It is however important for countries in this programme to meet certain requirements that are related to law enforcement, immigration enforcement, counterterrorism, document security, and border management.
Among the 40 countries in this Visa Waiver Program, you have South Korea, Denmark, Australia, Norway, Portugal, Greece, United Kingdom, Iceland, Sweden, Spain, and Austria, to name a few.
