Sent off Application 23 Feb 2018. In July my Canadian wife moved back to Canada to set things up that side of the pond. now I plan to visit in October for a 5 month Visit, hoping my PR comes through while there, while we look for a house, ( she is renting an apartment at the moment), my question is, do I change my address on my application to the Canada address or do I change it to my Son's address, as I will be moving out of my rented house when I leave and using his as a postal address, I'm retiring end of September.
