Establish yourself as a Colorado resident. To meet this requirement, you or your parents, if you are still a dependent, must be domiciled in Colorado for twelve months before the start of classes. Exceptions are made to this qualification if you serve in the military or have a job that requires significant travel or relocation.
Learn and meet the requirements of what it means to be "domiciled." To be considered domiciled in Colorado, you must be living in the state and provide evidence that you intend to reside there permanently. This means you must act and live in a way that would be expected if Colorado were your home. Ways to show this include graduating from a Colorado high school, voter registration, obtaining a Colorado driver's license, being permanently employed in Colorado or owning a house or other property in the state. A student under 22 who has lived with his parents in Colorado his whole life is automatically considered domiciled.
If you are under 22 and emancipated, you must also be domiciled in Colorado. To be considered emancipated, you must be married or your parents or legal guardians must sign an affidavit that releases them from all responsibility for your care. Emancipation can also be obtained if the state determines your parents or legal guardians have been neglectful in their care. If you are an emancipated minor, the twelve-month period for establishing residency begins once all official documentation is signed.
