I am divorced. I have just had an interview regarding to the Removal of Conditions: I-751. Interview lasted 15 minutes. Immigration Officer has not asked any evidence that would prove that marriage was real ( pictures, joint accounts, joint credit cards, joint insurance, etc). The copy of those documents were submitted earlier together with I-751. I was only asked about where I met my ex and what was the reason of divorce.Neither my expired conditional green card was taken away, nor stamp was placed in my passport. I was given an answer that I will be notified by mail. Is it normal or not? How long does it ususally take to hear from INS about the decision taken regarding to I-751? If they were going to deny my application, would they let me know during the interview or after? I do not know what to expect.Thanks in advance for advice and opinion.
