Hello Mahendra, admissions to engineering colleges in Tamilnadu are almost totally reserved for native candidates. Of course private engineering colleges and deemed to be universities can give admissions under management quota. To help you I am attaching a link that will give you details of eligibility for admission. Even though it's of last year, you can still refer to it and find conclusions.
