I'm a US citizen staying in Germany. My family has a summer home in Canada. I'm thinking of going to Canada this summer, and then going back to the US by driving from Canada into the US. I don't think this should pose any problems, but it's admittedly a convoluted way of going back. Anyone know if this is 'fine' and just a regular border crossing? Or do I need to give details of my entire time in Germany to US immigration?
I should clarify that I've been in Germany for the past three years studying. Last time on reentry to US airport wasn't a big deal, but they did require verification of identity etc. I know though that at the border between Canada and US they usually ask for some details of your trip and what you did. I guess I just give details about the time in Canada then?
