Stricter US entry rules may come into force as early as Monday. The tightening of rules intended by the Trump administration is intended to affect all visitors who come to the USA with the electronic ESTA application. ESTA is the common, visa-free authorization for tourists and business travelers from more than 40 countries that are part of the Visa Waiver Program (VWP). Austria is also among them. Scientists criticize the fact that this is intended to keep dissidents out of the country.
