Yes, as an international student in the UK on a Student Visa (previously Tier 4), you are allowed to work full-time during official university holidays. Here are some important details:

- During Term Time: You are typically allowed to work up to 20 hours per week (for degree-level courses) or 10 hours per week (for below degree-level courses).
- During Holidays: You can work full-time (usually up to 40 hours per week) during official vacation periods (such as summer, winter, and Easter holidays, as defined by your university).
- University Confirmation: The holiday periods are set by your university, so be sure to check your official academic calendar for exact dates.
- Postgraduate Students: For some postgraduate courses, especially those with dissertations or research components, there may not be defined holidays. Always clarify with your university before planning to work full-time.

Note: You must not take up permanent full-time positions or work as a professional sportsperson or entertainer.
