Second Masters after OPT expiration

[usindianguy]

I came to US in 2009. Completed my Masters in 2010 and I have been working on OPT since then. My OPT(stem ext) is expiring on 6/1/2013. Applied for H1B but was not approved(due to client letter issues). I am planning to go back to school starting Fall 2013 semister to get an MBA. The problem here is, after my opt expires, I get 2 months grace period to stay in the US, which is until 8/1/2013, but in many universities fall semister is starting on 8/19/2013. So, I am not sure, how this 18 days gap can be addressed (8/1 - 8/19). Can I remain in the US during that period ? Please advise.

Appreciate your suggestions/comments/feedback. Thank you !
