For how many months or years do we have to show the funds amounting to around thirty five to forty lakhs in UK/Australia?

You generally need to show your funds in your bank account for at least 3 to 6 months before your student visa application, depending on the country:

- For the UK, the funds must be held continuously for at least 28 days (about 1 month) before applying, but providing 3 to 6 months of statements can strengthen your case.
- For Australia and New Zealand, you typically need to show bank statements covering the last 3 months, though sometimes up to 6 months may be requested, especially if you have fixed deposits or large recent deposits.

Showing ₹35-40 lakhs for 3 to 6 months with clear, consistent transaction history is sufficient to demonstrate financial stability for your student visa application.
