No, it is not haram to do Wazifa for marrying a specific person. The question, 'Is it haram to do wazifa to marry a specific person?' is similar to 'Is wazifa for love marriage haram?' Which I have already answered that it is not haram. A Wazifa is like a Dua, a prayer made for a specific problem or need. Since marriage is a halal act, performing Wazifa for marriage is also halal, not Haram.
