Hello Riyaz,
After completing diploma in enginering, you can take admission through lateral entry in B.Tech programme. Admission is on the basis of entrance exam conducted by the University/college. However admission process and eligibility criteria vary from college to college. Let me know, if you wish to take admission in any particular college.
Good Luck!
