I am an undergrad in a state called X. I was originally living in state Y and have a Y state ID. Then I was declared independent and homeless. Does that mean I can be considered an instate student at any state graduate school?
Just to make things clear, I am not saying just because I have an ID, does not mean I am a resident.
Are your parents residents of state X, paying taxes there, and claiming you as a dependent? If yes, than you are a resident of state X. Generally speaking where you go to college doesn’t “count” towards residency.
What if I am an independent and homeless student and not filed any tax?
The rules that you need to follow depend on the state.
Texas
In general, yes, you retain your high school home state of residency when you go away for undergrad.
Who declared you independent and homeless? If it was your high school GC, it’s likely that will work for that state.
You can always get a state ID for the new state, but that doesn’t mean you will be instate for tuition purposes.
You have been in college 1 semester and you are worrying about grad school? It is unlikely you’ll still be homeless from another state in 3 years. Where are you spending breaks? Where are you spending summers? You’ll also have to file taxes as even if you don’t earn anything (and you should be working) you’ll have taxable scholarships for your room and board.
Don’t worry about things that far in the future.
During breaks, I stay on campus, during summer breaks, I travel to other countries for internships and volunteer activities. I have guaranteed spots for three summers to travel to China, Germany, and Peru. My scholarships are not taxable and I don’t have a place to stay. I was declared homeless by my high school district.
I love planning things way ahead of time and that’s how I live. I’m not worrying about it, I’m just planning my next moves. Based on the things I know from early on, I will polish my undergrad years into something that fit my future. Don’t worry, I’m not getting ahead of myself.
Are you sure? Any scholarship money that pays for non QEE (tuition, some fees, books) is taxable. Scholarships used for room and board, incidentals, travel is all taxable. You may not OWE any taxes on it, but it is taxable. All that summer travel, staying on campus, including over breaks? Taxable.
It may not matter. Once you graduate from undergrad, you are independent for FAFSA purposes anyway. You’ll list an address, and it may be your school address. Whether the grad school will decide you qualify for instate tuition is up to that state. Grad students often don’t pay tuition so it might not matter if you are a Texas resident or a NJ resident. Depends on what you are studying.
Look at the websites of the state schools you might be interested in for details on what is required for residency.
Nice to plan ahead. But first job now is planning what your first semester undergrad grades will be, focusing on that.
@Cjesusinme1 Unfortunately, you are getting ahead of yourself if you aren’t planning on filing taxes.@twoinanddone is correct. All $$ received beyond QEE (tuition, books, and only some fees (not all fees are applicable) is taxable. You may not end up having to pay taxes on it, but you definitely do have to file taxes and report it as UNearned income.
Didn’t you say you wanted to go to med school?
Let’s just say I am a resident of X state, which means I have an ID of that state. Then I go to an out of state undergraduate school in Y state. After completion of my undergrad, I go back to graduate school in X state again. Am I still considered an in state student?
They are perfect. I will have a 4.0 even if I don’t take my finals. 
well, around a 3.9 if I don’t take one final exam since I have an A-
@jym626 I don’t see a reason for you to ask me that question on this topic. Totally out of the subeject I asked about.
It has everything to do with the topic because you feel you’ve mentioned previously you are interested in middle school and if so the state it’s in would be discerned by where you are accepted. And it is additional future planning.
Typo is messed up the previous post. State of residence for grad school versus med school may, may have some different implications. Many posters have suggested that you take one step at a time. Adjust to your freshman year of college, work on making friends, and do well in school.Best of luck.
