How much does community matters in marriage?

So I love this girl. She is BC while I'm a MBC. We do belong to the caste tho(main caste is same, the division is different that's why the change in community). How much of a troble will this community will be? In terms of convincing their parents. I just want to know from a common POV. Ik intercaste is one hell of a headache to convince. Is this community thing would be the same level too? I'm not fully aware of how these things work. Let's meet know guys. Just from a general POV.
