To visit a person, use the verbal construction rendre visite à, which translates as to pay a visit to someone. You conjugate the verb rendre, which is a regular -re verb, and keep visite the way it is. Just remember to add the preposition à before the person or people you're visiting.
What is the difference between visitor and rendre visite?
Note that the verb visiter is used with places. When visiting people (friends, family...), we use the expression rendre visite à [quelqu'un] and never visiter alone. (This is similar to the English to pay a visit to [someone].)
