Hello NIMRAN !!

One of my friends who has studied 12th along with me, was from Bihar. When he went for document verification ,his documents where rejected. Because, he did not had residence certificate with him. They said that you or your parents must stay for 10 years in TELANGANA to get residence certificate. Only if residence certificate is there, then the process will continue and you can keep web options.

So, ensure that you are having residence certificate if you are eligible.

All the very best.
