My husband received his letter to appear for the oath ceremony after completing the naturalization interview. On the form, the box was checked off that he should bring a re-entry permit. I did a little research and re-entry permits are only required if you are going to be out of the US for a given amount of time. He was never out of the US for this amount of time (and was never required to obtain a re-entry permit), so I am confused as to why re-entry permit is checked off on the form. Did this happen to anyone else?
