Mismatch between I20 and Passport names and F1 Visa is already stamped !

[kryptonites]

Hi ,

My Passport states :
Given Name : YYYY YYY
Surname : -

US Visa F1 :
Given Name : FNU
Surname : YYYY YYY

Now, I realize that the I20 shows my name as :
Given Name : ZZZ
Surname : YYY

Now that there is a mismatch between I-20 and Passport, I wonder if I'll get stuck at the Port of Entry. Please Help !!
