It doesnt mention that they have to be inland as PR for 12 months.So its good to attach his PR copy along with 12 months proof of other documents.Docments of proofs of 12 months living must be availble Since he is living there from last 3 years (1 years as student and 2 years on work permit )and he got pr in july 2019. My question is that the condition of living from 12 months is for "after pr" or not ?
