Thanks for your reply.You can apply either one of them
Paper is the more common, if i go back in time i would prefer the online application since it can be updated instantly.
But for the most part it doesn’t really matter.
Another question, can I do medical check before submitting the pr application or I have to submit it first?
Also, Do I need to fill up the generic application form for all family or only one form for me and put their info in dependants section and this is consider that the all family applied for PR?
