Travel registered nurses are those nurses, who travel the whole country with a motive to help and treat people. They mostly work in place of those nurses who are on sick or maternity leaves. Furthermore, they are required at the time of emergencies, casualties and shortage of nurses. It is mandatory to be an RN first before becoming a travel RN. These nurses can work outside the United States as well, but they make much better money within the country. This whole profession offers tremendous benefits.
