For the two jersey schools, as long as you move in before 1st day of class you become state resident (to them in terms of financial aid)...as for being a "legal" state resident, that's another story.
University of Washington does after the first year- this is a very recent change. However, I think it is still hard for out-of-state applicants to get in (not counting MD/PhD applicants).
SUNY Upstate does - but don't know about the other SUNY's. What I do know is that ALL the SUNY's require proof of residency for a period of 12 months - but I don't know if this specifically means 12 months BEFORE you start first-year (with the exception of Upstate mentioned above)
