Can I work during my PhD?

Short answer: Carefully. The scholarship cannot be combined with other grants or research contracts, some calls set a limit on other income, and a study permit caps employment at 20 hours a week and 1,040 hours a year.

• Scholarship rules: no combining with research grants or other study grants, except money for stays abroad (University of Trento); some calls set an income ceiling, such as €14,000 a year at Tuscia (University of Tuscia decree).
• Permit rules: 20 hours a week and 1,040 a year for employment on a study permit (EU Immigration Portal).
• Teaching assistance and tutoring inside the university are common for PhD students. Ask your doctoral committee before taking any paid work, and get approval in writing.
