I got married with my US citizen ex-husband in August 2007. We filed and got 2 year GC in July 2008 with no problem. The decision for 10 GC was made on Aug 2010. My ex husband filed for divorce around April 2011. He did, however, put the date we separate on Aug 30, 2010. I didn't care the date and signed the paper work. Now I am applying N-400. Will I have trouble getting approved?
