Do I still have to show a bank statement of around ten lakhs for my student visa to Ireland even though my accommodation is taken care of by my sister who is already there?

Yes, you still need to show proof of funds for your Ireland student visa, even if your accommodation is covered by your sister.

Irish immigration requires all students to demonstrate access to at least €10,000 (about ₹ 10 lakh) for living expenses for one academic year, in addition to tuition fees. Free accommodation does not remove this requirement.

You can show this amount through your own bank statements, or your sister can provide her statements along with a sponsorship letter confirming her support.
