To
enter and depart Peru, you must have a valid U.S. passport. For
short-term visits of up to 183 days, a visa can be issued free of charge at the point of entry.
A Permiso Notarial de Viaje is a written, notarized authorization from the non-traveling parent(s). Peruvian immigration will not accept a document notarized by the U.S. Embassy or a document notarized by a U.S. notary in lieu of a Permiso Notarial de Viaje. This can be obtained at a Peruvian Consulate.
