Foreign visitors to the United States must clear U.S. Customs and Border Protection (CBP) to enter the United States. There is valuable information available to foreign travelers on the CBP website at www.cbp.gov/xp/cgov/travel [1], including what paperwork is required to enter the United States and sample customs declaration forms that will need to be filled out on arrival.
Many banks in South Dakota are not able to exchange foreign currency. In Rapid City [2], Great Western Bank (14 Saint Joseph St, 605/343-9230, Mon.–Fri. 8:30 a.m.–5 p.m.) is one of the few that can exchange most foreign currencies. If you are traveling on weekends, consider exchanging funds before you leave home or at major airport connections like Denver or Chicago.
