Go get a real hospitalist/nephrologist job on a waiver. Become a true doctor, not just a lifetime trainee (and possibly get a green card in the process). THEN you will have much better chances for a CCM fellowship (smart PDs will prefer somebody who doesn't need a lot of hand-holding).
No good intensivist will give a crap about your NeuroCCM fellowship. That fellowship shouldn't even exist, in the first place; it was invented only because neurologists and neurosurgeons wanted to protect their turf in the NeuroICU.
P.S.
@UHamdani, to be even clearer: any board-certified intensivist worth her salt can take care of a neuroICU patient, except for specific procedures such as EVD placement (which are usually done by neurosurg-trained people anyway). Who do you think used to take care of these patients? Neurologist/neurosurgeon + general intensivist. A NeuroCCM fellowship is a royal waste of time for anybody outside the neuro fields.
