Inland Application - Can he travel while waiting for the application to process?

[canuck_in_uk]

Ah, I am kind of freaking out here. How can I figure out if he has ever accidentally overstayed? How would we deal with that in our application?

We were careful to make sure he was never here for more than 6 months in every 12 month period.. but is that per year or just in the 12 months preceding his entry? I thought it was in the 12 months before the most recent visitor visa..?

He hasn't overstayed. This "6 months/year rule" is believed by many people and I think that a few CBSA officers have perpetuated it as well but there is no maximum amount of time per year that a visitor can be in Canada. As long as they have valid status, they can remain in Canada. There have been many people who have extended their visitor status for years without leaving Canada. This is perfectly legal.
