Is it possible to use my brother's income for visa sponsorship or loan co-applicant purposes in Australia/Canada?

Yes, you can generally use your brother’s income for visa sponsorship and as a loan co-applicant, but rules vary by country and lender.

- Visa sponsorship: Most countries, including Canada, Australia, and Germany, allow siblings to sponsor a student visa if they provide proof of income, relationship, and a sponsorship letter.
- Loan co-applicant: Many lenders accept siblings as co-applicants if they have a stable income and meet eligibility criteria. Some countries or banks may require the co-applicant to be a resident or citizen.

Requirements and acceptance are subject to change.
