Hi,
I have F1 till Dec 2010.
I went out of status becuase I did not register.
I was able to pull out following SEVIS information:

Termination : 02/22/2008 :TERMINATED (due to not registering)
ADIS Departure : 08/16/2008 : TERMINATED (I went back to my country)

Have I stayed over 180 days illegally?

Thanks.
