Here’s how in state / OOS tuition works, generally speaking.
If you are unmarried and under age 24, the school will look at the following:
- Where did you go to/graduate high school?
- What is your residence address, and for how long? What are your previous addresses?
- What is the residence address of your parents and for how long? What are their previous addresses?
- Where do you and/or your family members file taxes, and for how long?
- If you have been absent from your state for a long period of time, what was the reason?
The general rule is that if you’re a dependent student under age 24, your state of residence for tuition purposes is the same as your parents’ state of residence. For you, this will be Puerto Rico. There isn’t a way to change it because even if you list your sister’s address as yours, the rest of your documentation will show PR residency and you will be classified as an OOS resident for tuition purposes.
If you lie and get caught, you will face a variety of academic, legal and financial penalties, possibly including dismissal from school and/or being required to pay the difference in tuition, including back tuition, before you can continue with classes (assuming you’re still allowed to). It may even be considered fraud.
People have already told you that residency changes are not possible, but here are the details so you know where they’re coming from.
-
If you go to another state and attend school, your presence in that state will be classified as “for educational purposes.” In other words, you came to the state to attend school there. You cannon obtain in-state residency for tuition purposes while your presence is classified as "for educational purposes. This means that going to a CC and then transferring while hoping for in-state residency will not work. You will be OOS at the new school, too. Yes, even if you have an in-state address and driver’s license, and even if you’ve lived in that state for two years.
-
In order to obtain in-state residency for tuition purposes, you have to have lived in the state for two years without going to school. In addition, you’ll need to show things like proof of address, proof of a job, an in-state driver’s license, proof of paying in-state taxes, etc. And if you’re under age 24, you STILL might be classified as OOS if your parents don’t also live in your new state.
Some states only require one year instead of two, but seriously, it’s that hard. ESPECIALLY in California. There may be a few states that allow you to accrue time to residency for tuition purposes while taking classes, and I think Utah is one of them, so maybe look into universities in Utah.
- If you turn 24, are married or are a grad student, then you are no longer considered a dependent student and you will have an easier time getting in-state tuition if you move.
I am not saying this to be harsh. I get that your situation sucks, and that you really, really want to attend college somewhere other than PR. I wish we had easy answers for you. Unfortunately, we don’t.
Your best shot at college on the US mainland is A) see which schools might grant you in-state tuition because of the ongoing crisis in PR (Florida might), or B) attend one of the affordable options people have tried to help you find.
