I have a question. I have been travelling to the US since the last 4 years most of the times just to get gas (live very close to the border and gas is significantly cheaper in the states). 90 % of my trips were just for a couple of hours at max. However, I don't have all the dates when I went across the border. How important is this information while applying for citizenship. Should I just state what I believe to be true to the best of my knowledge or is there another way to approach this situation. I am sure there have been other people in the same situation as me. Any input would be most welcome. Thank you.
