Sorry to hear that.Would you mind asking you how many times did you visit COP? Before got the green card or after? Did you bring any documents with you which can proved you have emergency situation? and what DO you are in?
what kind of documents do i need to provide. The doc for why did i go back or why i was able to return to my country?
Only once did I visit COP, and it was after I'd gotten my green card. I did not bring any documents supporting my reason for the trip as I did not think it would be necessary. Also based on other asylee's N-400 experience, I thought I will not be put through this ordeal. I have yet to hear or read a N-400 being rejected due to visiting COP.
Its amazing there are some applicants that I know who went to COP multiple times but were granted approval, whereas my one visit, which I might add is due to a legitimate emergency, jeopardized my case.
