Can a tourist person file for a divorce here in the USA?What documents needed?

Assuming you hold a green card, you can file for divorce in NJ. I would also check to see if the Phillippines is a signatory to the Hague convention which means the country will honor the American court orders, You can file for adultery since the other wife remarried, and must send copies of the petition to the wife in the Phillippines.
