While applying for a UK Tier 4 ST visa, UKVI might ask students to demonstrate proof of funds as one of the eligibility criteria. Students can present bank statements or a letter of sponsorship of a minimum of INR 134,300 or £1,334 for each month of stay. This is evidence that they have enough personal savings to support a decent life during their stay in the UK. The funds in their bank account must not fluctuate for 28 consecutive days. While submitting their visa application, make sure that the statements are not older than 31 days.
