I know this question has been asked many times before but I've read different information regarding this.
I'm preparing to apply for my N400 and have decided to take my spouse's last name. We decided to keep our previous last names but have now changed our mind.
Is it pretty simple to request the change on the N400 form? I read that you can simply use a marriage certificate to change, but I would also like the citizenship paperwork to reflect the new last name.
