I received my green card (employment based) in May, 2007 and my wife got the same via my application. I would now like to apply for citizenship for the two of us. Early this year my wife had to move out of state for her employment and so lives and works in the state of OH. While i am continuing to live and work in the state of NJ and planning to move to OH late next year. Can i apply for N-400 for both of us in the same office? How exactly would this work, if it is possible. Thanks.
