The times listed below are not a guarantee of how long it will take to process your particular application. These times are to serve as an approximate guide only.
Processing times begin on the day our office receives a complete application and end on the day the final decision (i.e. approval/refusal) leaves our office.
“Working days” are days when the Visa Office is open for business. Weekends and statutory holidays are not “working days,” therefore do not count them when calculating processing times. Please note that visa office holiday closures may differ from local holidays.
This visa office will not respond to case status enquiries within the processing times above.
Please note that temporary resident visa, study or work permit applicants who do not include a legible 2D barcode page as part of their application should expect longer processing times (for more information, please see 2D barcode page).
