My spouse's interview happened earlir on June 17th and she received her oath letter during the first week of August. Her oath is scheduled for Aug 27 th in Concord, NH. My interview was on July 27th and I was approved. I went to Manchester, NH office today after setting up an infopass appointment, to see if I can sqeeze out an oath letter citing my wife's case. The lady looked up my file and told me that since my interview took place later than my wife, I will receive the Oath letter in due course with a September date. I requested her if Icould get the oath on the same day (Aug 27th) as that of my wife. I was told that the date was filled up and instead, I was handed a letter with an oath date of August 20th, which is an earlier date. I jut grabbed it. The earlier the better.
The Manchester DO office moved to a new premises recently, which is quite spacious. Now they have started administering the Oaths on the same premises. Untill last month, the Oath ceremonies were being held in the federal court in Concord, once a month.
My wife's oath on Aug 27 th is in Concord, while mine is at the USCIS office on August 20 th.
