Hopefully, many of you already know about this new law that come into effect on 1 Feb 2019.
If your child who is younger than 12 years old needs to switch from a DP to a student visa, then make sure you get this registry done. Your school will not be able to apply for the student visa unless the approval is given. The website says 2 weeks but the processing time is taking much longer (mine took close to 4 weeks) as the law is new and there is a back log.
I have pasted the link.

ps. No need to get this if you are simply renewing your existing pass or if you are switching from a EP related DP to a PEP related DP.
