I'm a Canadian citizen about to get my green card through my spouse. I also unexpectedly got accepted to a three year program at a university in Canada. One possibility for us is to move to a border town in the US and for me to commute to Canada for school (probably 4 or 5 days a week). As the drive is about an hour, I would probably stay overnight in Canada 1 or 2 nights a week, but with the departure date and arrival date counting as physical presence, I would be in the US at least 6 days a week. I'm wondering
If the constant short trips and the fact that I am going to school in Canada is going to be a problem for maintaining the green card (i.e. if CBP will get suspicious and try to get me to abandon)
If I could apply for citizenship after three years or if this will affect continuous residence. Or would I wait a year or two more to apply where I wouldn't have the short trips to Canada anymore because I'd be done with university.
Another option is to apply for a re-entry permit and delay the big move for 3 years until I finish. However, we make frequent trips to the US to visit my spouse's family so this may cause a hassle at the border (we do have Nexus).
A third option is to withdraw the application and redo the process when I finish university, but as it takes more than 2 years, I'd basically be applying again in a year.
Thanks for the help.
