I am filling out my forms and in Part 8, as a filer from part 1b (spouse of US), it requires me to itemize all the travel outside of the US in the last 3 years. I live in upstate New York and it's a short drive home to where I'm from in Canada and I visit quite frequently. I did not keep a list of all of the times I crossed to visit my family. Each time I crossed using my 10year Green Card. No visits were longer than one week. Is there a way to look up this information?
