Hello Rahul.

If u r filling the admission form of any state college in Haryana and want to use ur caste certificate there then it won't work there. For state colleges u must be having the caste certificate of that state only.

But if u are filling in any national colleges for example through JEE MAINS then u can use ur reservation there  by procaliming ur certificate of Bihar.

Thanks for contacting us and ask for any other query.

Good luck
