Theyre both US Citizen, but my dad is retired so we mostly lived in bases and didnt really have our own house
While on active duty, your dad would have had a declared state of residence where he would have paid state taxes, if applicable, and voted absentee when he was stationed elsewhere, regardless of where the family lived or what kind of housing arrangement they lived in. Mom or Dad don’t have a voting registration card from a District in a state anywhere?
Not trying to push you too hard on this, just shining a light, as I said above, in case there is something that can be used.
During my Navy career, I established residency in Jacksonville, FL, based on a rented condo I lived in. I never lived there again, but I was registered to vote in FL based on that residency and District. I lived and worked out of state, voted absentee faithfully, never lived there again. Of course, the great attraction of FL was no state income tax, and I was able to maintain that residency while I was a “temporary military resident on orders” in FL, HI, VA, MD, CA, RI, etc. Once I retired from active duty, I became a resident of the state I lived in.
I realize you are in a different situation, as I don’t know how it works for U.S. citizens residing out of the country, whether your parents are registered to vote anywhere. If they are, that is your District, or if they are required to pay U.S. taxes and have a state declared - I am sure others have found themselves in this situation before, which is why I encourage you to discuss it with Admissions.
Don’t hesitate to apply unless Admissions tells you otherwise. The USMMA Superintendent MAY have some discretionary noms he controls.
