Hey Preethi

To be eligible for local area quota in Andhra Pradesh you must have studied in an Educational Institution in such local area for a period of not less than four consecutive academic years ending with the year of your qualifying examination (10+2). Or else you must have studied there in the past at one of the institutions in the local area for a period of not less that seven years.

The local area under Osmania University (O.U.) area, it includes the districts Mahabubnagar, Ranga Reddy, Hyderabad, Medak, Nalgonda, Warangal, Khammam, Karimnagar

Hope this is helpful
