As a student in the UK, you can get the special discount facility for your life needs such as a discount for tax payment. If you decide to stay off-campus with others who are not students, you will need to discuss in advance what you can contribute together. In the meantime, perhaps you should take the B1 cefr test to get the UK visa as well.
Many students there are looking for odd jobs during college there to earn extra for their living expenses. For foreign students, UK regulations only allow you to work a maximum of 10 hours per week. With a minimum wage of £ 6.19 for workers over 21 and £ 4.98 for 18-20 year workers, you can earn a decent addition. Especially if you work in London, many companies pay based on London’s minimum wage of £ 8.55 per hour.
If you decide to look for odd jobs, you can also take advantage of special discounts as employees at your place of employment. You can take advantage of these discounts to shop for clothing or electronic equipment where you work. Or you can work in restaurants that usually give free meals to their employees.
