What conditions do I need to apply for a work visa after I graduate from Italy? How many years can I work? What does permanent residence mean? thanks a lot

you need to find a full-time job with a regular salary within a certain range before you can apply for a work visa. There is no limit, but the employer will generally only give you a contract of no more than 3 years. Many contracts will be shorter. Permanent residence means that you can live in this country indefinitely, even if you have no job. In addition, after you have permanent residency, you can enjoy many national treatments except the right to vote, and you don't need a work permit to find a job.
