Re: Family PR Formalities

Just email ICA to explain due to COVID and the kids schooling schedule, you do not want to disrupt their education and request to postpone the appointment to a period where it is more conducive for the whole family to come down to proceed with the formalities.

Re: Family PR Formalities

Quite honestly I don't think he even has the option of just proceeding with PR formalities for his wife but not his kids. The IPA for his wife is pertinent to his kids being included in the whole application i.e. their applications aren't independent of each other. It is quite possible that had he applied for his wife alone (without including his kids), she would have been rejected.

Re: Family PR Formalities

It will definitely sent the wrong signals. This is becaused of the fact that one child is a male and will incur an NS obligation if getting PR. Too many people have tried to find ways around this inherited obligation and basically all they do is throw up potential minefields for the future of their children by limiting their choices once the reach the age of majority. The government here has a very long memory and it is also a very good possibility according to one mouthpiece of the government that families that try to do work-arounds with regard to NS issues may well find their ability to get their OWN REP renewed when it comes due. That could really ruin you day as well. Additionally you have already let the government know what you are planning (by trying to remove them from the IPA). Your ship has a leak in it and frankly if you go through with it, I foresee problems later. Maybe sooner than later.......
