If you want one number first, it is this: after graduation, Italy gives you 12 months on the Permesso di soggiorno per attesa occupazione. That is a residence permit for job-seeking after graduation, and it comes with full work rights. If you find a job, you can convert it to a work permit.
That is useful, but it is not the same as “settling in Italy.” The real question is whether 12 months is enough time for you to find a role that matches your degree, your language level, and your salary expectations. For many students, the answer depends more on the city and the course than on the visa itself.
Italy is not the easiest country if your plan is to land, work quickly, and move straight into long-term residency. It is better if you are choosing a degree with a clear job market, especially in engineering, architecture, design, data, or management.
