It's easy to become a Washington State resident. To become a resident of the state of Washington, simply take some action that proves you intend to live in the state on more than a temporary or transient basis.
Examples of actions you can take:
Voting Rights
For information about residency and voting rights, refer to
the Frequently Asked Questions on the Secretary of State website.
Social and Health Services
There may be additional residency requirements in order to be
eligible for certain social services and/or health services.
See the Residency Requirements section of Department of Social
and Health Services website for more information.
College Tuition
To qualify for resident tuition, state law requires that you
be a state resident for 12 months. The University of Washington
has a guide to help determine eligibility at http://www.washington.edu/students/reg/residency.html.
More information about residency requirements that apply to students
in the state of Washington is available at the Higher Education
Coordinating Board's Student Residency website.

The Department of Revenue has also established a definition
of residency for sales and use tax purposes which can be
viewed at http://dor.wa.gov/content/contactus/con_residdef.aspx.
