W. Va. Code § 56-1-1
(a) Any civil action or other proceeding, except where it is otherwise specially provided, may hereafter be brought in the circuit court of any county:
(c) For all civil actions filed on or after July 1, 2018, a nonresident of the state may not bring an action in a court of this state unless all or a substantial part of the acts or omissions giving rise to the claim asserted occurred in this state: Provided, That unless barred by the statute of limitations or otherwise time barred in the state where the action arose, a nonresident of this state may file an action in state court in this state if the nonresident cannot obtain jurisdiction in either federal or state court against the defendant in the state where the action arose. A nonresident bringing such an action in this state shall be required to establish, by filing an affidavit with the complaint for consideration by the court, that the action cannot be maintained in the state where the action arose due to lack of any legal basis to obtain personal jurisdiction over the defendant: Provided, however, that the provisions of this subsection do not apply to civil actions filed against West Virginia citizens, residents, corporations, or other corporate entities.
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.
