To establish legal residency in a new US state:
Locate a place to live in the new state. Purchase a home if you can.
Spend substantial time in the new state.
Maintain social and business relations in the new state.
Have a bank account in the new state.
Next, establish a living address with the U.S. Postal Service by going to the nearest post office and filing a change of address form.
Have your important documents transferred to your new address (insurance, memberships, licenses, etc.).
You will then need to find a job, pay taxes, and file tax returns in the US state in which you seek residency.
Obtain a driver's license and car registration in your new US state, or apply for a non-driver's state ID card if you do not drive.
Next, register to vote in your new state.
If you have professional licenses, have them transferred to your new state.
