Greetings Mukunthavanan!

It's good to know you're preparing for police service, it's a tough job and requires a lot of mental and physical strength. There are two ways by which you can apply for police service in Tamil Nadu. Assuming that you're looking forward to starting with the cream layer in police service either you can apply for Tamil Nadu Public Service Commission(TNPSC) or through Union Public Service Commission. The details regarding the same are as follows.

For TNPSC, a candidate should be domicile to the state and can appear for Group B, C level of service entry. Since it's a state-based allotted service by the state government hence, candidate those who qualify this exam will be instated in TN police service and work across service district within the state.
