Which specialty?

The most important thing is to find a specialty that you will enjoy. And remember, most NICU's are located in larger cities, though not always. You are most likely not going to be in a romote area as a NICU nurse. It depends on what you like.

The most in-demand specialties for travel nurses are ICU, ER, OR, L&D. There is also demand for peds, NICU, med/surg, etc, but the demand isn't quite as high.

I don't necessarily agree with ERRNTraveler. If you are a med/surg nurse, you can get an assignment anywhere. It also goes for ER, ICU, and OR. Not sure about L&D. I do know (and have recently heard) that there is a huge demand for pediatric nurses (staff, as well as travelers). They're even offering huge sign on bonues.

The more you have to offer (i.e. ACLS), the more assignments you can find.
