Which paper actually travels
Graduates think first of the parchment, and that is rarely the paper to use. What the counter wants is a certificate from the student office naming you, your course and the day you finished, signed by someone in that office. It is quick to order and quick to replace if a file goes missing abroad.
This is where how to apostille a Degree Certificate differs from most paperwork: you choose the version before anyone stamps anything. Ask the reader abroad whether they need the degree alone or the exams with it. Order both if the answer is unclear, since a second round at the registry costs more time than the extra sheet.
The desk, and the signature it checks
A certificate from a state university is an administrative paper, so the Prefettura, the state office for the province, adds the stamp. Court papers and deeds signed before a notary are judicial or notarial, and they go to the Procura della Repubblica instead. If your school is a private one, ask the counter first which route it treats your paper under.
The signature is what ties the job to one city. To apostille a Degree Certificate in Genoa the person who signed for the student office must be someone that province's counter can check against a sample. Where a school never deposited a signature, the clerk may ask the registry to confirm it, and that adds days you should plan for.
Fee and timing
The apostille cost for a Degree Certificate in Genoa is a €16 tax stamp per document, and some documents are exempt. The university may charge its own fee for issuing the certificate, which that office sets. Allow for two waits, one at the student office and one at the counter. Visa deadlines are the usual reason people wish they had started with the registry.
Where the stamped degree is used
Work visas ask for it, so do licence bodies for nurses, engineers and teachers, and so do universities weighing an application for a master's place. Some employers use it to set a salary band. Italy has been in the Hague Apostille Convention since 1978, so its member states accept the single stamp on the registry's paper.
Language, and the details to check
Almost every reader abroad will want a translation, and many want it sworn in front of a Tribunale, an Italian court, so the wording counts as accurate. Keep the course title close to the Italian and let the translator explain rather than invent a local equivalent. The rules to apostille a Degree Certificate in Italy hold in every province, but each licence body abroad sets its own list.
Read your name, the date you finished and the course title against your passport and your job application. A middle name on one paper and not the other is enough for a slow reply. The legalisation of a Degree Certificate in Genoa for a country outside the Hague list runs through more offices, so ask that employer early which chain they expect.
