Hello. our petition was sent back to uscis under 221g last year July 2015.However, we give another shoot to k1 visa as she got some compulsion to marry me in India. This time they just gave me white slip which however does not say 221g but says AP and state that the consulate will contact me as soon as the AP done. my petition is about to expire have and I still to notify about their final decision. Don't know if my petition will extend or not.
