Duties in the field depend on the project and situation of the mission country. Generally nurses are involved in clinical activities, supervision, and training of national medical personnel, with some administrative duties.

The general criteria for working in the field are at least 2 years of professional experience in relevant fields, availability for at least six months, current professional credentials and relevant work or travel experience outside the U.S. Assets that benefit applicants are flexibility, community service projects, adaptability to basic living conditions, and foreign language skills.

Once a mission is confirmed, MSF will be responsible for all travel, visas, and relevant vaccinations. Field workers should assume responsibility for routine health maintenance vaccinations
