Necesitas una una ETA para Guam si tienes un pasaporte surcoreano

Travelers need a travel authorization to visit Guam for Business or Tourism. The Electronic System for Travel Authorization (ESTA) is an online application that determines the eligibility of visitors to enter Guam. Once the application is approved, travelers receive their ESTA confirmation electronically. A valid ESTA is required to visit the country. If the ESTA is expired or doesn’t match the traveler’s passport information, travelers will not be able to board their flight. An ESTA is electronically linked to a passport and valid for 2 years. If travelers receive a new passport, they must apply for a new ESTA. United States permanent residents or holders of valid United States visas don’t need an ESTA.
