W. Va. Code § 16B-17-13
(b) Notwithstanding the provisions of subsection (a) of this section, a complainant may institute an action against a respondent in the county wherein the respondent resides or transacts business at any time within 90 days after the complainant is given notice of a right to sue pursuant to this subsection or, if the statute of limitations on the claim has not expired at the end of such 90-day period, then at any time during which such statute of limitations has not expired. If a suit is filed under this section, the proceedings pending before the commission shall be deemed concluded.
The commission shall give a complainant who has filed a complaint a notice of a right to sue upon: (1) The dismissal of the complaint for any reason other than an adjudication of the merits of the case; or (2) the request of a complainant at any time after the timely filing of the complaint in any case which has not been determined on its merits or has not resulted in a conciliation agreement to which the complainant is a party. Upon the issuance of a right to sue letter pursuant to subdivision (1) or (2), the commission may dismiss the complaint.
Notice of right to sue shall be given immediately upon complainant being entitled thereto, by personal service or certified mail, return receipt requested, which notice shall inform the complainant in plain terms of his or her right to institute a civil action as provided in this section within ninety days of the giving of such notice. Service of the notice shall be complete upon mailing.
