"The U.S. Embassy wishes to inform U.S. citizens living and traveling in Argentina that in recent months, U.S. citizens have reported a number of crimes to the embassy. Crimes reported include petty crime, taxi scams (especially at international airports), mugging, snatch-and-grab robbery involving motorcycles and bicycles, and occasionally more serious crimes such as express kidnapping, home invasion, carjacking, assault, and sexual assault using date rape drugs. We recommend that U.S. citizens traveling and living in Argentina always be aware of their surroundings, maintain a high level of vigilance, and take appropriate steps to enhance their personal security. Please consult reliable sources for information on transportation, lodging, and the general security of areas you are visiting.
U.S. citizens should avoid areas of demonstrations and exercise caution in the vicinity of any large gatherings or protests. The majority of crimes reported to the Embassy occur in the major metropolitan areas but U.S. citizens should use an equal level of caution outside large population centers. While crimes happen at all times of day and night, they are significantly more frequent after dark.
The Embassy does not have evidence that victims have been targeted because of their U.S. citizenship. If you are the victim of a crime, please report it immediately to the police and inform American Citizen Services at the U.S. Embassy."
