A residency question for tax purposes: In 2011, I was living in California under F-2 visa till June, over June-Oct I was working in Washington state under OTP (Optional Practical Training) status, and since Oct 2011, I have been under H1-B visa working full time in California again. And apparently, I am not a permanent US citizen, that's why I am under visa. Now my question is:
1) Am I considered a California resident for state tax purposes?
2) Which state form should I use for filling taxes?
Thanks a lot!
