If I am sponsored by the government, is there any requirement to show ITR (Income Tax Return) files in UK/Australia?

No, if you are sponsored by the government for your studies abroad, you usually do not need to provide your own Income Tax Return (ITR) documents.

Instead, you must submit official proof of your government sponsorship, such as a sponsorship letter detailing the amount and duration of support. This is accepted by countries like the UK and Australia as evidence of financial capacity for student visa applications.

Visa requirements can change, so always follow the most current guidelines for your destination country and university.
