Can I sit for the CPA in one state and work in another?

I am looking to get my CPA this summer. I have planning on moving from Georgia to Texas. In Georgia I meet the requirements to sit for the exam  where as in Texas I do not. What are the most important decision points in deciding which state to sit for the exam in? Can I be certified in one state and work in another? Can I transfer my certification from one state to another? Thank you.
