Have you made an application to UNLV? Have you been accepted? Have you filled out FAFSA? Have you gotten a financial aid package and a statement of cost of attendance? Have you researched what UNLV’s rules are for getting instate tuition?
The answers to all of the above are likely “NO”.
Before you get too set in your plans, start with that last question. You need to look up and read up on UnLV’s In state tuition requirements. If you are not an independent student defined as over age 24, a veteran, have a dependent, married, ward of state, homeless, you are still dependent on your parent’s finances as well as your own for financial aid, and likely for state residency requirements when it comes to in state tuition.
I do not know what the rules are for UNLV’s in state tuition. You have to look up this info to see if it is possible for you to get state residency for tuition purposes on the university’s web site. State residency for library privileges, car registration, driver’s license, tax purposes do not entitle you to a state school’s rates most of the time. There are specific rules for that.
You also need to apply for the transfer, get accepted, apply for financial aid , see what you get, and check if any merit money is available for transfers and how to apply for it
Usually OOS schools are not generous in giving dependent students in state tuition the way you are thinking of getting it. There usually is very little money from the school for financial aid or scholarship for OOS transfers. The federal government has PELL if you are eligible and the Direct Loans.
So you need to do some research about all of this. Good luck
