What about exiting and re-entering during inland application, what should I say at the officer for reason of entry? At that point I can't be vague about the application I guess as they will be able to see that I have been staying in Canada for a long time and probably even see I have applied for spousal sponsorship? Are there reports of officers being tough on proof of ties to my home country? I mean... if I applied for spousal sponsorship, obviously my plan A is to move to Canada, so it is difficult to keep ties for 1+ year in the home country... does the officer consider this fact when dealing with people who applied for spousal sponsorship or are we treated like any other temporary resident?Money remaining in Norway is a start. Again, they don't seem to spend a lot of effort worrying about ETA visitors on arrival at airports. Just answer briefly and relaxed. Tell them you're here to wait out the norwegian winter, that'll get a laugh. Or that you'll go to spain and wait on the beach. Or you have vague plans of some kind or another.
(Illegal immigration from Norway is not a huge issue here)
