Nursing is one of the world's largest health professions, but "nurse" is not one universal job. Registration level, specialty, work setting and country regulation can change both the role and the route into it.

WHO's State of the World's Nursing 2025 describes nurses as the largest occupational group in the health workforce and continues to highlight workforce shortages and international migration. In the United States, BLS currently projects registered-nurse employment to grow 6% from 2025 to 2035, with about 180,800 openings per year on average. Those figures describe the U.S. RN market, not every country or specialty.

What nurses do

Nurses combine observation, communication, documentation, coordination and direct care within their legal and professional scope. The exact responsibilities depend on registration, specialty, employer and country.

Nursing levels and titles

Common titles can include:

  • Registered Nurse (RN);
  • Licensed Practical Nurse / Licensed Vocational Nurse in parts of the U.S.;
  • Enrolled Nurse in some countries;
  • specialist nursing titles;
  • advanced-practice roles.

These titles are not globally interchangeable.

Major nursing specialties

Important career directions include:

  • medical/surgical and acute care;
  • ICU/critical care;
  • emergency;
  • perioperative;
  • pediatrics;
  • neonatal;
  • mental health;
  • maternal/newborn nursing roles;
  • oncology;
  • cardiac;
  • community/public health;
  • home health;
  • occupational health.

Non-bedside directions include informatics, education and management.

Hospital vs community vs non-bedside paths

Hospital work often involves shifts, structured multidisciplinary teams and higher-acuity workflows. Community/home roles tend to involve continuity, travel and more independent coordination. Informatics, education and management move the emphasis toward systems, learning or leadership.

Registration/licensure basics

Registration is country- and jurisdiction-specific.

The United States regulates nursing through state/jurisdiction boards. The UK uses the NMC, Ireland uses NMBI, Canada uses provincial/territorial regulators with NNAS involved in credential assessment for many internationally educated nurses, and Australia uses Ahpra/NMBA processes.

Professional registration and immigration are separate.

How to choose a specialty

Compare:

  1. patient population;
  2. acuity;
  3. pace;
  4. work setting;
  5. schedule;
  6. autonomy;
  7. amount of family/community interaction;
  8. prior experience expected.

Do not choose only by title or salary claims.

How to become job-ready

Build evidence around:

  • current registration status;
  • placements or practice experience;
  • communication;
  • prioritization;
  • documentation;
  • escalation;
  • teamwork;
  • role-specific competencies.

Never add a clinical skill to your resume merely because the job description mentions it.

International nurse pathways

A useful sequence is:

target country → regulator → qualification recognition → language/competence requirements → registration decision → job search → immigration/work permission

The exact order can vary, but professional registration should never be confused with a visa or employer sponsorship.

Cluster navigation

Use the specialty pages to compare careers, the resume/interview/skills pages for job readiness, and the UK/Ireland/US/Canada/Australia pages for current registration routes.
