First of all I would like to thank you for your prompt response, but you still didn't answered my query. I know that there are two certificates one is for Central and second is for state. My query is that, my caste is in OBC category in Delhi and in UP, but not in Central. I am a resident of Delhi and having OBC certificate issued by Delhi government. So can I apply in UP too as my caste is in OBC category in UP?
