I worked in NC for a while till July 2007. Then I left for AZ to do a PAID INTERNSHIP untill January 2008. Now I am back to my full time job in NC. On my 2007 Tax Returns, how should I claim my residency? If i decide to go back to school, is there a possibility that my school might make me pay out-of-state tuition? Please help.
Thanks in advance.
