Hello,

As a Muslim girl, you can definitely prepare for the CBI (Central Bureau of Investigation) exam. However, when it comes to the uniform, CBI officers usually wear formal attire (shirt, trousers, coat, etc.) and do not have a strict dress code like police or defense forces.

Wearing a hijab may depend on the department’s internal rules, but it is generally allowed in many government jobs. However, an abaya (long cloak) may not be allowed during duty hours, as officers are expected to wear formal office wear.

Hope it helps !
