Further review of HB 1808 shows that the exception reads very similar to Texas law. You can still get in-state tuition provided you graduated from OK HS, lived there for 2 years with parent/guardian and applied for legal status. However, if there is no way to apply without risk of deportation, the last part is waved.

Section 3242
The Texas law requires 3 years in Texas, not 2.
Thanks for the info, I knew all the states but I didn’t know the details. No, I don’t agree with it, but it’s amazing that it’s not just Texas, isn’t it. ;)
