If i get a learner permit, will it affect my N400 application process?

It would be a good idea to get a learner’s permit in the state in which you file for naturalization. You would be able to show such at the time of your naturalization interview as a further demonstration that you actually reside in the state of application. I assume that you applied for naturalization 90 days or more after moving into the new state or that the two states are covered by the same USCIS field office.
