Hii.. Bhupendra 

Domicile is not needed by any of the centralised university taking admissions on the basis of all india entrance exams.  domicile is mostly required when you are applying for the state universities like UPTU or University of Maharashtra.

i hope this serves your query good luck to you...!

Hello Bhupendra, CLAT is a national level exam for LAW to National Law University, it does not need any domicile certificate to apply for CLAT across India. However, during the time of admission some NLUs have a few seats reserved for students of that particular state. Having a domicile certificate would be helpful at that stage.

Example - Domicile is needed only when you are planning to give any state level exam (eg MH CET) other than your own state.Under domicile, you will be considered citizen of same state (Like Maharashtra even if you are from other state) and you will get preference while applying...
