Yes, you can stay in Europe after graduating from your studies. In many European counbtries, graduates have options to stay and find jobs through post-study work visas or residence permits. For instance, Germany provides an 18-month visa for job seekers, while France permits graduates a year to either get employed or start a company. Once you have work experience and meet residency needs, you can apply for permanent residency. Because policies differ among countries, it is best to confirm local rules.
