If you have dual citizenship and a valid European passport, you can enter the United States with this authorization. It is processed online up to 72 hours before traveling.

Argentines who have a European passport can enter by processing the ESTA. The ESTA application costs US$21 per person. The same permit allows multiple trips to the U.S. without the traveler having to request an ESTA authorization each time they travel. To keep in mind: the traveler can only stay a maximum of up to 90 days on each trip.
