He has to do something now. He need to go get the kids he has as much rights to them as she does. He needs to file temperary custody orders with them in his possesion. If she has already filed he is screwed but he needs to get the kids closer to seattle. If he fights this all the way through and the kids stay in Vancouver he will be screwed. get a lawyer right now. She cannot keep the kids with no visitation see the kids as much as possible. IF you get screwed and she gets to stay in Vancouver make sure he puts the burden of transportation in writing on the mom. If she doesn't pay for transportation she will be in contempt. Get off this board right now and get a lawyer.
If you can't afford one you will need to beg steal or borrow he has the under hand right now and will get nothing without a lawyer and the longer he waits the worse off for him.
Call Galliger in Seattle Divorce attorneys for men <-- that is a really a joke but being a man in WA these are really the only lawyers left that will represent men in a female state.
