Can letters of recommendation be arranged from professionals outside my university, such as professors from other universities in UK for a Master's?

Yes, you can arrange letters of recommendation from professors outside your university, as long as they are familiar with your academic abilities, skills, or achievements.

UK universities accept LORs from professionals who can provide credible and detailed insights into your potential for a master's program. Make sure your recommenders can speak specifically about your strengths and suitability for your chosen course.
