Change of course/ program after Visa interview in the same univeristy

[Edla]

Hi

I have a question I have applied for MBA & my visa got approved on MBA I20. After receiving my MBA i20 I have requested my university if they can transfer my course/program from MBA to CIS .Initially they said they cannot guarantee my admission and I need to serve 2 months notice period so I have attended visa interview with MBA I 20 just a day after my visa got approved they issued me CIS I20 with same SEVIS id. Will that be a problem for me at port of entry ?

Thanks in advance
