I had my naturalization interview over a month ago. I passed English and civics and was given a N-14 to resend 3 pages of N-400. Officer wanted me to fax the documents. N-14 due date was 30 days so i did not take a chance and decided to mail them as well. what is the average time to get the oath letter? he also hand delivered N-652 which congratulates and says that i established naturalization requirements.
