Travel nursing professionals work through travel nursing agencies. There are several hundred such agencies in the United States. Many of them hold Joint Commission certification. If you wish to work for a Magnet hospital or a major academic teaching hospital, it is best to choose a certified agency. Once you are signed on with an agency, the agency staff works with you to help you find an assignment that fits your qualifications and preferences. Expect an application process for each assignment, including a remote interview. As you prepare for your interview, bear in mind that you are interviewing the healthcare facility staff just as much as they are interviewing you. In other words, you should ask specific questions designed to help you determine whether the assignment would be a good fit for you. You may wish to ask about the ratio of patients to staff, for example, or whether there will be mandatory overtime.
