If your parents work for the Central Government outside Himachal Pradesh, and your schooling wasn't in HP, you will need to obtain documents from the authorities responsible for each document in the place your parent is employed or where you reside.

Key documents and issuing authorities

1.Proof of Central Government Employment: Your parent's employing department or office will issue this document.

2.Domicile Certificate: If eligible based on your parent's permanent residency in HP, despite serving elsewhere, the Tehsildar/Revenue Authority in HP where your family has their permanent residence will issue the domicile certificate.

3.Educational Certificates: The education boards where you completed your 10th and 12th grades will issue your mark sheets and certificates.

4.Other documents: For other documents like photographs and ID proof, you can obtain them from the usual authorities.

Hope it helps..
