What is the normal processing time for a Student Dependent Visa ?
Normal processing times can vary depending on the location of the applicant, and on the numbers of applicants at any specific time.
A current notice on one Embassy website is:
Processing times for Student subsequent entrant visa applications processed by New Delhi are currently longer than the published global visa processing timeframes across all sectors. We have received a high number of applications for subsequent entrant applicants and are seeking to process them as quickly as possible.
I saw one being granted 15 months after application.
Some applications take longer for various reasons.
I have seen some people being advised to wait until immigration request medicals, before getting them done. This can delay an application.
The instructions on the same Embassy website says:
Important Information for Student Subsequent Entrant Visa Applicants
The Department of Home Affairs (Home Affairs) prioritises complete applications where the applicant has also cleared Australia’s health requirements.
