Some permanent residents live close to a U.S. border and have family or business purposes for routine trips across the border, in Mexico for example. When applying for U.S. citizenship with Form N-400, you should make every effort to document the dates of these trips, particularly trips that are 5 days or longer. However, after 5 years, these trips can be too numerous. So how you should list regular trips in Part 9 “Time Outside the United States” of Form N-400 when these trips are frequent and numerous too many to list on the form?

For such cases we recommend you to document each individual trip outside the United States if possible. If you have frequent and regular trips outside the U.S. that are too numerous to list individually, you may include an attachment that explains your history. Write “See attachment” in the space provided for the country in Part 9, Item 3. You must be sure to include a separate sheet of paper that describes the time outside the U.S. to the best of your ability.

By way of example, you can write the following:

“N-400 Addendum: Part 9, Item 3: Time Outside the United States.

During the past 5 years, I made regular trips to (City, Country) that are too numerous to accurately document with detailed dates. These trips were for the purpose of (provide a reason). I generally made the trip (frequency e.g. twice a month); I would cross the border on a (e.g. Friday and return to the U.S. on a Sunday). During the last five years, I estimate that I made (x) trips that lasted (x) days per trip. Therefore, I am estimating that I spent a total of (x) days outside the United States for this regular trip.”

This template is a starting point, you can modify it to meet your needs. Upon completion, print a copy and place it behind your N-400 application.
