The required bank balance for a UK student visa (Tier 4) depends on various factors, including the duration of the course, location of study, and whether you^re applying from inside or outside the UK. Generally, you need to demonstrate enough funds to cover your tuition fees and living expenses. As of recent guidelines, this could range from around £1,334 per month for living costs in London (for up to 9 months) to £1,023 per month for living costs outside London (for up to 9 months). Additionally, you may need to show proof of tuition fee payment or sufficient funds to cover them. However, it^s essential to check the specific financial requirements outlined by UK Visas and Immigration (UKVI) for your circumstances before applying.
