Thank you so much. I am just worried because they don't have their old passports.
My parents are having their interview for naturalization in the same center. They don't have their old passports but i tried to get all of their tickets they used to travel outside of the United States. The longest trip is 5 months.I couldn't find one of the tickets though for a trip in 2016 which is not stamped on the new passport they have. They don't file taxes but I claim them on my taxes as dependent. Does that work as a proof for their physical presence? Their interview is next week?
