I stayed in Canada from October 2023- September 2024 so I ended up extending my stay which then authorized me until March 2025. I am back in the US and plan to spend summer in Canada this year. Since my extended stay lasted until only March do I need to extend my stay again? I plan to be there from end of May to August with a couple trips back to the US in between. I’m unsure if I would be able to travel there without extending my stay even though I am only there for a shorter period of time. Anybody have any info on this?
