Yes 

I think you should change it as soon as possible because you will not be able to have benefits of the creemy layer.

OBC Creamy layer does not get any benefit.They does not come under reserved category anymore.They are treated equal to General category candidate.The difference between Creamy and Non creamy layer is on the basis of Annual income of Family.If the annual income of the family is more than 4.5lakhs per annum,the candidate is considered to be under Creamy layer and does not get any benefit of reservation.The Union ministry is considering to raise the bar to 6laks per annum and it will be done this week itself. OBC non creamy layer gets benefits for exams and jobs.
