It is advisable to contact the Paraguayan Embassy in Washington or one of Paraguay's consulates in the United States for specific information regarding customs requirements. While in a foreign country, a U.S. citizen is subject to that country's laws and regulations, which sometimes differ significantly from those in the United States and may not afford the protections available to the individual under U.S. law. Penalties for breaking the law can be more severe than in the United States for similar offenses. Persons violating Paraguay's laws, even unknowingly, may be arrested, expelled, or imprisoned. Penalties for possession, use, or trafficking in illegal drugs in Paraguay are strict and convicted offenders can expect jail sentences and heavy fines.
Prison conditions are harsh.
Americans living in or visiting Paraguay are encouraged to register at the Consular Section of the U.S. Embassy in Asuncion and obtain updated information on travel and security in Paraguay.
