International travel

General information

U.S. passport application processing times

The U.S. Department of State expects a significant increase in passport applications in 2016 and 2017, which may cause processing times to increase. It's recommended that U.S. citizens submit passport applications and renewals well ahead of planned travel. Also, beginning January 1, 2016, U.S. citizens can no longer receive passport page inserts, so if you’re running out of pages, you may want to renew now even if your passport is not expiring.

For information on how to apply for or renew a passport, go to the U.S. Department of State's Passport page.

Argentina Reciprocity Fee

American, Australian and Canadian citizens are required to pre-pay a Reciprocity Fee for entry into Argentina. The fee was previously collected at Argentine airports upon arrival; however, customers must now pay the Reciprocity Fee online through Argentina's National Immigration Agency website before checking in for their flight to Argentina. A barcoded receipt for payment must be presented to a representative at check-in.

United is not permitted to transport to Argentina any American, Australian, or Canadian citizen who has not paid the Reciprocity Fee prior to departure. Failure to provide a copy of the barcoded payment receipt at check-in will result in a delay or possible denial of your travel to Argentina. Please visit for complete details, including the fee amount and the validity period. Any questions regarding this fee or the payment process should be directed to the Argentine authorities.
