N400 - dates of leaving US ?

[kalvario]

12/28/2008 is a date I became a permanent resident – date of issuance of my green card. I would like to submit N400 to become a citizen. Does anybody know where to get records about your departures of the country ? they ask about how many days you were out on page 4. I have an arrival stamp so I can figure out when I came back ..but I don’t keep a records of when I left …any ideas ? thanks so much

Do you patronize an airline or two? If so, you can look at your frequent flyer mileage statements. Thats what i did for many of my short trips for work, otherwise I maintained my own records for vacations, etc. Do note that you have a stamp into the country that went to, and an arrival stamp back in the US. The best way is to go page by page and list all the stamps and dates and correlate the two sets. Hope you dont have too many. Good Luck!
