Which is my state of residensy If I am studying University in Illinois and my parents moved to Arkansas in 2022 and they claim me as a dependant?

Determining your state of residency can depend on various factors, including where you plan to live and work, where you have established significant connections, and the specific laws of the state in question. Generally, your state of residency is considered to be where you have significant ties, such as:

Where you are employed.
Where you have registered to vote.
Where you have a driver’s license.
Where you own property or rent a residence.
If you do not intend to return to your parents’ home after graduation, and you establish these connections in a new state, that state could become your state of residency. However, each state has its own rules regarding residency, and some states may require you to live there for a certain period (often at least one year) before you are considered a resident for tax or tuition purposes
