Hello Mahesh,
After completion of your Diploma you have almost 10 years of work experience. Now with this work experience there is perhaps no need to do graduation in engineering because you would be de factor considered as an engineer.
However, for acquiring other educational qualification you need to do your graduation first in any subject that you like. Here I will like to suggest you to go to the webpage of a famous Distance Education University IGNOU. Here you will find plenty of subjects that you will like. Provided, this what you want to do. If you have earned enough in these 10 years, then you can think of branching off into doing some social work which will satisfy your inner self.
