A friend of mine, who is eligible to apply for N-400, might need to move to a different state in about 3 months. He's thinking that he will apply for N-400 right now. He might have to fly back for the interview and/or the oath ceremony.
Anything that he should watch out for -- from the perspective of the N-400 process?
