The answer will depend on whether the person passed the boards. Regardless of any possible shortage, fail the boards and forget about residency or licensing in any state even if it's just to clip nails. As far as I know, every state requires passing boards to obtain a license. If I'm wrong, I stand corrected.
If you do pass your boards and don't obtain a program, you must first assess the reason. Then the suggestions above are fine until the next cycle.
