I am a F1 student visa holder, entered into United States in Fall'2010(August 2010) for my Master's. I thought I would graduate in Spring'2012 and applied for an post-OPT. I got my Employment Authorization card in Spring'2012, whose start date is 06/09/2012, but I could not graduate as I got very poor grade in one of the course and so I had to repeat it. I did that course in Fall'2012 and got graduated in 17th of December 2012. Now I got a job and working for a software firm.
My question is: I was unemployed for around 6 months and now when I consulted my University International office people to update them with my employment details they said I am Out of status and can't help me. Please tell me further steps that I need to go through to be in-status. Please help me.
