Hi,
The admission in all the medical colleges now is through NEET. So you need to appear in NEET and clear it.
Now the seats in any state are divided into - 85% seats reserved for the state candidates and 15% all India quota. As you do not belong to Tamil Nadu, you will be treated as a candidate through 15% all India quota and would be admitted through the same.
You can get further information regarding on the link given below -

Hope this helps.
Good luck.
