Hello Student,

Your OBC Certificate of Haryana is Valid only for Haryana State Counselling.

In NEET-UG Central Counselling, if your caste JAT included in OBC NCL Category then you need to obtain another OBC NCL Certificate from the concerned authorities. For this detailed information is provided in NTA NEET-UG Brochure 2020, Download the Brochure of NTA NEET-UG 2020, Go on the Page no.84 Appendix XI download the pro forma (Form) of OBC NCL Certificate and Fill it and get is signed and attested by concerned Authorities.

In Delhi NCT Jat included under OBC Category. But  as far as I know in Central list JAT doesn't included in OBC NCL Category so you can not claim reservation in Central Government Institutions and Institutions of Other State, if you want to take admission in Delhi then you need to obtain OBC Certificate from Delhi Government but you are not a Resident of Delhi so they will not give you OBC Certificate. So your current OBC Certificate is valid only for Harayana State.

This is the Official link of National Commission for Backward Classes: http://www.ncbc.nic.in/user_panel/centralliststateview.aspx you can check that in Haryana list, JAT doesn't included in OBC NCL Central list.
