E visa for another wife

[F_KITTY]

I am a frenc citizen legally separated with my husband. He is now living and working in CT with an E Visa. Our divorce is not final in France, I am living in France with my two children. . I found out he has got married with someone in Las Vegas and I have procured their marriage certificate.

I was wondering if my hunsband had asked for a spouse E Visa to his another wife (bigamous of course)? Could you please advise me where should I address my enquiry on this matter? For your information, they didn't register their marriage to the General French Consulate in Los Angeles after their marriage in Las Vegas.
