Argentina requires a travel visa for citizens of some countries. You can check the list here: https://www.migraciones.gov.ar/accesible/indexdnm.php?visas.
To get the visa, your passport should still be valid for 6 months after your visit, so please verify the expiration date on your passport.
If you require a visa, please contact the LOC as soon as possible at uhecr2024@auger.org.ar.
