I did my higher education in a country with an Agreement with Argentina, so I was speed tracked. In your case, you should follow the steps outlined in this page of the Ministry of Education: https://www.argentina.gob.ar/educacion/tram…es-sin-convenio
The Argentine Embassy in Algeria has a page outlining the steps, specifically for Algerian titles: https://earge.cancilleria.gob.ar/es/content/emp…-en-argentina-1
In my experience, getting your title validated is just a matter of paperwork uploaded on the Ministry of Education website. The will issue the certificate as a digitally signed PDF.
With that, you can enroll into any University in Argentina. The admission requirements (in terms of language knowledge) vary depending on the institution where you are going to apply and the program you are interested into.
First, thank you for the comprehensive answer, but there is still something that is not clear to me.
Is the equivalency certificate required by all universities, or only public ones?
