回复：谢谢你，住够没住够，是和学生有关，还是和家长有关？

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.
