In a civil action where more than one plaintiff is joined, each plaintiff must independently establish proper venue. A person may not intervene or join in a pending civil action as a plaintiff unless the person independently establishes proper venue. If venue is not proper as to any such nonresident plaintiff in any court of this state, the court shall dismiss the claims of such plaintiff without prejudice to refile in a court in any other state or jurisdiction. When venue is proper as to one defendant, it is also proper as to any other defendant with respect to all actions arising out of the same transaction or occurrence.
For purposes of this subsection, "nonresident" means any person, whether a citizen of this state or another state, who was domiciled outside the State of West Virginia at the time of the acts or omissions giving rise to the claim asserted: Provided, That a member of the armed forces of the United States who is stationed beyond the territorial limits of this state, but who was a resident of this state at the time of his or her entry into such service, and any full-time student of any college or university of this state, even though he or she is paying nonresident tuition, is considered a resident under this subsection.
