I don't know what is exactly meant by the these document requirements:
1- certified copy of the high school diploma with apostille;
2- translation of the high school diploma into Italian performed by an official translator (sworn at the Court) and equipped with apostille;
Now, am I required to do two apostilles, this is impossible, because Apostille is issued for a single unique document, either as original or legalized, not translation.
What is meant?
