What does it mean to show 28 days old funds for visa application in UK/Ireland?

To meet the “28-day rule” for your UK or Ireland student visa, you must show that the required funds for tuition and living expenses have been held in your bank account for at least 28 consecutive days before your visa application. The balance cannot drop below the required amount during this period. The final date on your bank statement must also be within 31 days of your application. Only liquid funds in a recognized bank are accepted, and assets like property or shares do not count. Following these rules is essential for your visa application to be considered valid.
