I was out of status for a semester because we forgot to renew my i 20. However I was continuing the classes. Then I re-entered to US with new i20 and sevis (No issues) and came back to status in 2009. Now I am filing my 485. I am confused whether I have to mention it or not. My lawyer is saying , since I entered US with new i 20, I dont have to mention.
Please suggest whether my lawyer is correct or I have to mention.

Thanks in advance.
