HELP!! Is it okay to receive I-20 after admitted semester starts?

<p>Hi,</p>

<p>I'm an international student currently attending a university in U.S. on F-1 visa and got accepted to U of Illinois at Urbana-Champaign (UIUC) for Fall 2011 for Math program.</p>

<p>I'm taking two summer classes now at the current school, and Internatioanl Center in my school told me they have a rule that they can release my SEVIS record after all grades are posted.
UIUC can issue an I-20 after the current school release my SEVIS record.</p>

<p>Summer semester grades are available on Aug. 16, but UIUC fall semester will start on Aug.22.
Getting I-20 usually takes two weeks or more, so I think I will not be able to get the I-20 from UIUC until the fall semester starts.</p>

<p>So MY QUESTION is,
"What happens if I don't have I-20 from UIUC until the fall semester starts?? Can I take fall classes at UIUC? Should I request to defer my admission to the next semester??"</p>

<p>Internatioanl studenets, PLEASE HELP ME!!!! It's really not my fault at all...I'm worrying about it so much........
I'm now in U.S., it's not a problem related to entrance to the U.S.</p>

<p>If you are in the US, I don’t see this as a problem… But phone in and see, and I wouldn’t worry too much, if there were to be any problems I’m sure UIUC would have notified you.</p>
