Hy Abhishek Kumar,

Yes, you can definitely use your Bihar caste certificate . If validity is procured and in some cases, u need to have NCL (Non-Creamy Layer) certificate, then the state castes are considered. For JEE they generally consider SC, ST & OBC.

Thanks,

As a domicile of West Bengal, you should typically use a caste certificate issued by the state of West Bengal for JEE Main application. Using a Bihar caste certificate may not be appropriate unless you have valid reasons and documentation showing your eligibility for it. It's essential to follow the guidelines provided by the exam conducting authority and ensure that the documentation you submit aligns with your current domicile status and eligibility criteria.
