In the egalitarian U.S.A., I don't know of a state that does not guarantee a four year education.
You might have to start off in junior college/community college, but if you graduate from high school, you are guaranteed admission in JC, community college, state college, university (expenses are another thing).
If you graduate from JC/CC, you are guaranteed admission in a state college/university (expenses not guaranteed).
That is my experience with California, Louisiana, Hawaii, Alaska, Nevada.
