REQUIREMENTS FOR U.S. CITIZENS TO OBTAIN VISA TO ENTER ARGENTINA
U.S. citizens do not need a visa for tourist or business travel to this country. A valid U.S. Passport is required.
A v isa is required for Official and Diplomatic passport holders.
Any other U.S. citizen who wishes to travel to Argentina for any purpose other than tourism or business negotiations (e.g. work, study, adoption, immigration, or stays longer than stipulated in the entry requirements) should contact directly, the embassy or nearest consulate.
REGISTER YOUR TRIP:
The U.S. Department of State encourages all American travelers to register with their local Embassy or Consulate when arriving in a foreign country. Registration helps the Embassy to provide important services for American citizens residing or traveling abroad. Some of these services include:
Locating individuals in cases of family or personal emergencies,
Relaying important travel and safety information about the region,
Arranging evacuation transportation in cases of natural disaster or civil unrest,
Issuing replacement passports when originals are lost, and
A number of other administrative services relating to personal documentation.
Without the information provided through registration, the Embassy is severely hindered in its ability to provide these services. Many of these services involve emergency situations and time constraints, therefore failure to register will almost certainly lead to delays at moments when you can least afford them.
