N-400 Time outside the US

[vsharma57]

Since I received my green card, I visited Canada couple of times and never got stamped on my passport as Green Card was enough to enter Canada. I don't remember when I visited, how many times and how long I stayed in Canada. Where can I get my dates of travel to and stay in Canada for Part 7 of N-400 form for naturalization?

I'll highly appreciate any help me in this regard. Thank you.

Try to remember as much you can and write that down.
