Allowed early entry on F1

[Yash Kabra]

I entered the country 45 days before instead of 30 days. 
The immigration officer acknowledged the violatioin; checked my documents and made an exception and allowed me to enter the US on F-1. (I also have a Valid B2) I have F1 stamped entry on my passport.
Now the university is ready to activate my SEVIS but have warned me that because of my early allowance, I may face problem in the future.
Do I have to Re-enter even if technically I'm on F1?

You would do well to discuss the situation with the firm of Murthy or any of your choice or leave and return if your college is a reputable one. I take it that the college wants you to leave and return.
