I am married to a US citizen, and I am aware of the rules regarding when I can apply for citizenship. I entered the USA 5 years ago and married immediately (as the K1 instructs). I received my conditional permanent residency, and applied for removal of the "conditional" status after the two year period. Because of the huge delay in processing these cases, we have only just had our interview. The result of the interview was a recommendation for removing the conditional status, but we will have to wait again as new regulations mean the CIA performs another background check (understandable after 9/11). My status has been extended for another year while this takes place. Are we able to file for citizenship at this stage, or must we wait possibly another year for the background check and the completion of my current application?
