Thanks silence43 for your suggestion,but I still have confusion regarding my situation...

Can I  apply for H1B,even if I do NOT have the certificate of my degree( MS for my case),provided that I get the OPT prior to my graduation ?My particular case is I am getting the certificate on May  2008 only,but I will get my OPT,if approved, on March,because I have already satisfied all the requirement for MS degree.Will you mind clarifying me ,if you know about this situation?
