Hello Aspirant,
In concept, subject to the particular qualifying requirements of the institution, you should be able to utilise a valid EWS certificate issued by the Bihar government to claim reservation benefits in any government or public sector institution in India. It is usually a good idea, nevertheless, to confirm the eligibility conditions and particulars of the organisation you are applying to. To find out if it accepts EWS certificates from other states or if there are any special criteria for EWS certificate holders, you may get in touch with their recruiting department or visit their official website.
