Your funding can come from a variety of sources, such as private funds, university funds, sponsoring company / agency / government funds.
For self sponsorship of stay where the student is presenting funds in their own bank statements, then only the bank statement of the past 3 months has to be provided with the finances required for the first year.
If your funding comes from multiple sponsors, each sponsor needs to provide an A4 sponsorship letter, along with bank statements, previous year’s income tax return (ITR), 3 months’ salary slip and an identity proof.
Students receiving scholarship grants must produce a statement indicating the amount and duration of their grant on the letterhead of the granting organisation.
If the required resources are guaranteed by an individual residing in France the student must produce a signed statement of financial responsibility, a photocopy of the national identity card of the guarantor, and proof of the guarantor's own financial resources (such as the guarantor's three most recent pay stubs and most recent tax return).
