UK

As an international student, one can work upto 20 hours per week during studies. However, there is no limit on the number of hours international students can work during their semester breaks or vacations.

The UK has very strict rules when it comes to work hours for international students and therefore, students are advised not to exceed the work hour limit, as doing the same could lead to the revokation of the UK study visa and subsequently, deportation from the country. 

The recommender must mention at least three qualities of the applicant and then provide a suitable example for each quality to convince the admissions committee. Mentioning a lot of qualities without substantiating them with examples will not sound strong/ convincing.

The LOR format for UK is no different from those for US or any other country. The LOR should be one page or approximately 500 words in length. The font and size should be consistent and readable, for instance, Times New Roman 11 or 12 point size. The LOR can be academic or professional, showcasing the eligibility of the candidate.

The recommender must establish his association with the candidate right in the beginning of the LOR and later discuss at least three qualities of the applicant and provide suitable examples to back his claims.

Someone who has been a British overseas territory's citizen by connection with Hong Kong can be entitled as the British National (overseas), (BNO). A British National (Overseas) Visa allows BNOs and applicants from Hong Kong to come to live and work in the UK even without having a job offer. 

This visa also opens ways to permanent residence after a period of years in the UK and the recipients also become eligible for benefits like certain public funds to support their living in the UK.
