Multistate license question

[nurse1903]

Currently a graduate student in Texas with an out of state clinical assignment. Both states are compact states. I plan on keeping my primary state of residency as Texas by not getting a new drivers license in the new state where my clinical is. I'll be there for a little over a year, but don't plan on staying long term. Do I need to get a single state license for the clinical spot or will my current multi-state license hold up? 

The BON website is confusing and the NCSBN website says as long as I don't change my primary residence that's good enough (the example is changing your drivers license).  Does anyone have experience with thissituation?
