Hi everyone, I have applied for fall 2011 but couldnt get visa for fall .I did not lose hope and applied for spring2012.My visa was rejected first time for spring yet i tried again n got it.I was running out of time and couldn't go .So i have differed my admission to fall 2012.Will this cause a problem for me at the port of entry .And i also wanted to know about my sevis fee.I have paid it in june 2011 .But i would be leaving in august 2012.Will this cause a problem.Do i need to pay sevis again??
