In addition to being subject to all Argentine laws affecting U.S. citizens, dual nationals may also be subject to other laws that impose special obligations on Argentine citizens. In some instances, dual nationality may hamper U.S. government efforts to provide protection abroad.
Foreign citizens may encounter difficulties attempting to exchange Argentine pesos for dollars and other foreign currencies. In complying with Argentine foreign currency exchange regulations, banks and exchange houses in Argentina reportedly have been refusing to sell dollars and other foreign currencies to foreign citizens in exchange for pesos unless the foreign traveler is able to present original receipt(s) showing the purchase of pesos. Even with the original receipt(s), tourists reportedly have only been able to buy currencies worth the same or less than the original peso purchase(s). Therefore, tourists who might want to exchange pesos for foreign currency upon leaving the country should retain all receipts related to the purchase of pesos during visits to Argentina. The purchase of Argentine pesos does not appear to have been affected, whether in exchange facilities or via ATMs using U.S. debit cards. Commodity exchange is not one of the services provided by United States embassies for U.S. citizens abroad. Travelers should exercise caution when approached with offers of illegal exchange at rates more favorable than the official rate; there have been some incidents of scams in which travelers were robbed, some of them at gun point.
Argentina’s mountains, forests, deserts, and glaciers make it a popular destination for outdoor and adventure sports enthusiasts. Despite the best efforts of local authorities, assisting visitors lost or injured in such remote areas can be difficult. U.S. citizens have died in recent years while mountain climbing, skiing, trekking, and hunting in Argentina. Travelers visiting isolated and wilderness areas should learn about local hazards and weather conditions and always should inform park or police authorities of their itineraries. Reports of missing or injured persons should be made immediately to the police so that a search can be mounted or assistance rendered. Argentina boasts the highest peak outside of the Himalayas, Mount Aconcagua. Its billing in some guidebooks as affordable and "requiring no climbing skills" attracts hundreds of U.S. citizens every year. With its 22,840-foot altitude, bitter cold, and savage storms, however, even experienced climbers should bear in mind that it is one of the world’s most difficult and potentially hazardous climbs.
