Are international students in the UK allowed to work? 

Yes, international students in the UK are generally allowed to work, but there are some restrictions on the number of hours they can work per week depending on their visa category.

Tier 4 (General) student visa holders are allowed to work for up to 20 hours per week during term-time and full-time during vacations. However, they cannot work as a professional sportsperson or coach, or as an entertainer.

Students on short-term study visas are generally not allowed to work in the UK, but there may be some exceptions depending on the specific circumstances and visa requirements.

It's important to note that international students should always check their visa conditions and restrictions before starting any work in the UK, and they must not exceed the maximum number of hours allowed per week as this could lead to the cancellation of their visa.
