This requirement has resulted in a particular problem involving petitions filed on behalf of registered nurses. Although many such nurses possess advanced degrees, they are filling nursing positions in the United States that generally do not require advanced degrees. Specifically, the Occupational Information Network (O*Net)[10] indicates that, in nursing, only managerial jobs (director of nursing or assistant director of nursing) or advanced level jobs (such as clinical nurse specialist, nurse practitioner) generally require advanced degrees. A registered nurse job, by contrast, usually does not require an advanced degree.
