There are a number of Doctor of Nursing Practice (DNP) programs available online. Most take two to four years to complete, depending on your level of preparation, the specialty you choose, and the particular program. Costs vary by program--you'll need to contact the school directly to find out how much it will cost.

Since you are practicing outside the U.S., it's crucial to research the programs thoroughly before you apply. Many programs are designed for nurses who live and work in the United States. The most important issues to consider when evaluating an online DNP program are:

• Does the program require on-site instruction?
• Can clinical courses be completed in your home country?
• Does the required coursework meet your needs as an African medical practitioner?

Most advanced nursing programs require a clinical component and some on-site training. On-site training usually involves two to four campus visits per year, either week-long or weekend sessions. As an African resident, it's important for you to consider whether travel or temporary residence in the United States is an option.

• If so, look into obtaining a student visa from the U.S. Department of State.
• If not, contact the admissions department of each school to discuss your options as an international student.

You may be able to satisfy the clinical requirements through the work you already do in your private practice.

Once you find a program that accommodates your needs as an international student, it's time to evaluate its course offerings. A DNP program that emphasizes Nurse Administration will be of little use to you unless you plan to work with U.S. health insurance companies. If you choose to continue in Gerontology, make sure the program focuses on general epidemiology and health leadership rather than on issues specific to U.S. health care policy.

Start with online research into particular programs, and once you've narrowed your search, contact the admissions counselors by email or phone to iron out the details.
