Visas applications to visit the Argentine Republic can be submitted to any Consular Representation of the country. If you are an argentine citizen and want to invite a foreign citizen to Argentina, you can send him an Invitation Letter or to the Embassy depending on the reason for the trip. It must be certified by a Notary Public. In the case of being a company, civil or sports organization, it must also be registered in the National Registry of Applicants (RENURE).
Once the documentation is received, the Consular Section will contact you to coordinate an interview. It is personal and mandatory. The mere fulfillment of the formal requirements mentioned does not guarantee the granting of the visa, being an exclusive prerogative of the Argentine state.
If you have any other query, you can send an email to firstname.lastname@example.org
