<p>Generally, you can always petition to change residency classification once you have met the required conditions. In this case, your daughter is your dependent and you will be moving in say June, 2-3 months before school starts. I am assuming your daughter is your dependent and you will be paying for some or all of her expenses. </p>
<p>At the end one year, you can request a change in classification and the reason is that you had job transfer and intend to be a Washington resident. As long as you have done the right things (rent or preferably buy a house, get a bank account, file Washington Income tax returns ) you have a legitimate case. Call the school and tell them that you are looking at job transfer and you have questions about residency and they should be able to confirm. I do not see an issue as long as it a legitimate move and you have the documents to prove it.</p>
