Travelers can reduce the likelihood of encountering such incidents by taking the same precautions that they would take in the urban United States. The loss or theft abroad of a U.S. passport should be reported immediately to the local police and the nearest U.S. embassy or consulate. Banks are a major exception. All banks and businesses are required by law to close on Sundays and national holidays. Foreign diplomatic missions in Seoul generally maintain strict business hours.
Smaller shops tend to be open from early morning until late evening every day of the week.
For longer stays and other types of travel, visas must be obtained in advance. Applicants must depart and apply for new visas at an embassy or consulate outside Korea. In Korea, outlets for both 110 and 220 volts are usually available, although many newer hotels have only 220 volt current. Always check the voltage of the power supply before using equipment. In outlying areas drink only bottled or boiled water.
