What Is This Application Form Letter?

The form (PDF 1300t) is the official application used by the Department of Home Affairs for anyone applying for Australian citizenship. It includes sections for personal details, residency history, and a declaration letter confirming your eligibility.

How to Fill the Form Online

• Enter text directly into each field.
• Save your progress and return later.

Common Mistakes to Avoid
