I think you still have to wait 12 months after the marriage. Or, if you are 24 or above, after moving here one year, file the state tax and all that. Or, if you are under 24, but financially independent, meaning that your parents “abandoned” you, your parents are not living in the states, you are filing taxes independently for at least 3 years, then after moving here one year, you file CA tax for that year, you will be considered CA resident.
