I am a green card holder and I live in the states. I am petitioning for my spouse. My spouse is a citizen of Iran and so am I. I have noticed that there has been changes in the wait time of green card holders applying for spouse and the priority dates according to July, August and September 2013 visa bulletin was "Current" meaning no wait time? But It has stopped since September 2013. Is there any knowledge of future expected time? How long should I expect to wait from the time we file the petition until the day our priority date becomes current if we file within a month from now?
