Hello all
I have double nationality.
I have a 2 year visa on one of my passeports, which expires 1 month before my actual plain ticket out of Canada.
Before its expiry I will be taking a trip to the US.
I was thinking of filling a request for an eTA on my other passport. Would that be legal?
Or would it be possible to prolong my original visa when reentering from the USA, without applying online?
Thank you!
