回複：謝謝你，住夠沒住夠，是和學生有關，還是和家長有關？

What Lyon said is not completely right, otherwise, all F-1ers should be eligible to in-state tuition after one year. The fact is it depends on the policy of the state and specific institutuion. In my state (GA), for public schools, if 485 pending for more than 12 months, you will be treated as in-state student.
