Hello,

If you are studying in Tamilnadu from 4th standard to 12th standard and your father or mother working place is Tamilnadu then you can get a residential certificate or Tamilnadu. Because you live there so long and completed your board examination also. If you have residential certificate in Tamilnadu then you can apply for 85% state quota counselling round. There will be no issues occur.

All the best.
