My husband and I will take our oath and become naturalized U.S. citizens on the 25th of this month. We have a 17-year-old daughter who currently holds a green card, but her 10-year card is set to expire in November of this year. My question is: after we file her N-600 following our naturalization, will she lose her permanent resident status if the N-600 process isn't completed before her green card expires?
