My Mother's N-400 application was just recently denied due to residency requirements. She had not lived in the uscis district filed from for 3 months. While this was expected by me as we had realized this after filling but the thing that annoy' us is that the application was denied after she was finger printed and interviewed her. She passed the interview too. In the denial letter they have said that she can appeal with a $600.00. We have decided to file a new application. Has anyone gone through this situation and taken a different route than us in getting the citizenship? Thanks.
