What type of sponsorship letter is needed for a DTV visa application?

To apply for a DTV visa, there's a requirement for a sponsorship letter if you're applying as a dependent. This letter is typically used when a dependent, like a spouse or child, is applying based on the primary visa holder's DTV status, indicating that the primary holder will be responsible for their financial support. However, if you are self-employed and applying for your own DTV visa, a sponsorship letter is not relevant to your situation.
