Department of State
The US Department of State, often abbreviated to “DoS”, has a similar function to the Ministry of Foreign Affairs. The Department of States is headquartered in Washington, D.C., near the White House, where the U.S. President officiates. It covers nearly 139,000 m² of space in which more than 8,000 employees work. This federal executive department is responsible for international relations. As such, it has several hundred embassies and consulates in nearly 190 countries around the world. All of these points of contact with the American administration allow you to complete the formalities for travel to the USA.
The Diplomatic Security Service (DSS) is the diplomatic security service. It is one of the most developed departments of the DoS and ensures the security of diplomats and American citizens abroad.
The State Department was directly involved in the creation of the Visa Waiver Program, the program that created ESTA. He worked in conjunction with the Department of Homeland Security (DHS). From this association was born a program designed to facilitate the travel of nationals of the beneficiary countries who can thus travel safely without having to apply for an American visa.
