I got married to an USC in my country. However, after coming here things changed dramatically and marriage resulted in a divorce in one year in dec 2005. She had applied for divorce. However, I had got my CPR by then which was valid until jun 2007. I filed for the waiver and got one year extension which is valid until jun 2008. However since we were married in my country, I have the certificates and photograph and some emails from there. She had cleverly never tried not to mingle the finances so I donot have nothing to show from here apart from the divorce decree . I can give the affidavits and photographs of wedding etc. My question is whether it would be a sufficient proof to show the marriage was bonafide ? And how much time canI expect for the interview ?
