Is there a validity period for applying for immigration to Australia?

Yes, according to the regulations of the Australian Ministry of the Interior (the former Immigration Bureau), the vocational evaluation of skilled immigrants is always three years, and the vocational evaluation report that exceeds three years is invalid, even if the validity period indicated in the evaluation report exceeds three years. Please note that under the current EOI- skills selection immigration system, visa officers judge whether the evaluation report is valid according to the time when they receive the invitation.
