My question involves criminal law for the state of: Virginia/Washington State

My husband transferred here to Virginia 3 months ago from Washington state. A month ago Washington brought new charges against my husband and now a lawyer told me that Virginia is going to reject my husbands transfer even though he has been here for 3 months. Is that possible? The new charges were not pending at the time of my husband's transfer...

And if it is possible, will Washington extradite him through mandatory retaking or will he have to return to Washington voluntarily?
