Do I need a passport or visa to enter?
A valid passport is required for U.S. citizens to enter Argentina. U.S. citizens do not need a visa for visits of up to 90 days for tourism or business. Argentine law requires that, prior to arrival in Argentina at any entry point, U.S. citizen tourist and business travelers must pay a $160 reciprocity fee by credit card online at the Provincia Pagos website . Once paid, you must print out the receipt and present it to the Argentine immigration officer at the time of entry. The fee is valid for ten years from the date of payment and multiple entries. It is advisable to keep multiple copies of the receipt, as it must be presented every time you enter Argentina. The fee applies only to bearers of tourist passports. Travelers bearing diplomatic or official passports are required to get visas prior to arrival in Argentina but are not charged the reciprocity fee, nor are travelers transiting and not entering Argentina.
U.S. citizens who arrive in Argentina with expired or damaged passports may be refused entry and returned to the United States at their own expense. The U.S. Embassy cannot provide guarantees on behalf of travelers in such situations, and we encourage you to ensure that your travel documents are valid and in good condition prior to departure from the United States. Different rules apply to U.S. citizens who also have Argentine nationality, depending on their dates of U.S. naturalization. For more information, check the Argentine Ministry of the Interior website. Argentine-born naturalized U.S. citizens who enter Argentina as temporary visitors may depart using their U.S. passports as long as they remain no longer than the period granted by the Argentine immigration officer at the time of entry (typically 60-180 days). Travelers in this category who overstay will be required to obtain an Argentine passport to depart.
Children under 18 years of age who reside in Argentina, regardless of nationality, are required to present a notarized document that certifies both parents' permission for the child's departure from Argentina when the child is traveling alone, with only one parent, or in someone else's custody (click on the "international parental child abduction" link below for more information).
U.S. citizens wishing to enter Brazil or Paraguay from Argentina are required to obtain a visa in advance from the Brazilian and/or Paraguayan embassy or consulate nearest to the traveler's place of residence. Please note that this requirement applies to the popular cross-border day trips many travelers take when visiting Iguazu Falls. Travelers transiting between Brazil or Paraguay and Argentina should always make sure to present their passports to Argentine immigration officials to have their entry and exit from Argentina recorded. The U.S. Embassy in Buenos Aires cannot assist travelers with obtaining Brazilian or Paraguayan visas.
