Authority over visas to enter the Italian Republic is vested in the Italian Ministry of Foreign Affairs and its network of accredited diplomatic and consular offices, which are responsible for ascertaining that applicants are in possession of the requisites entitling them to obtain a visa, which is issued by the diplomatic or consular mission with territorial jurisdiction over the place of residence of the applicant.
The authority issuing Uniform Schengen Visa (transit or short sojourn) is the diplomatic mission of the Schengen State present locally which is intended to be the sole or main destination.
Where it is not possible to identify the main destination, in case of several stages in the journey, the visa shall be issued by the diplomatic mission of the Schengen State of entry.
The authority issuing a National Visa (long sojourn) is the diplomatic mission of the Schengen State present locally in the place intended to be the long sojourn destination.
If the Contracting Party competent in issuing the visa does not have a Mission in the alien's country of residence the Uniform Schengen Visa can be issued by the Mission of another Contracting Party on its behalf.
National Visas may not, however, be issued by delegated authority.
The possession of a visa does not give an alien automatic right of entry to Italy, because the border authorities may always refuse entry to an alien who is not in possession of adequate means of subsistence or is unable to provide full details regarding the circumstances of the sojourn in Italy, or for reasons of security or public policy.
No visas (and no extension to previously issued visas) may be granted to aliens who are already on Italian soil.
In exceptional cases the border authorities may issue a transit or short-term sojourn visa (Art.35 of Visa Code).
