Looking for a special MSN program

You are having a hard time finding a nurse practitioner program that meets your goals because for the most part, the existing NP tracks limit us to the broad, population-centered, programs geared towards delivery of health care in the US setting. Based on what you said in your post, a good start would be to narrow your search by looking into FNP programs. This will offer you the widest scope of training in primary care for all age groups. It would still be geared towards American healthcare in terms of following national guidelines for treatments/therapeutics that are in line with US standards. As such, you will be required by regulatory boards to complete hours of clinical rotations in approved facilities that meet these standards in order to be certified. However, there are most likley some programs that could assist you in arranging for elective clinical rotations/placements for extra credit outside of the US, maybe in Mexico and parts of Latin America, who knows maybe even Africa. You will need to call or make arrangements to meet with faculty from various programs to find out which ones are able to do this. That's really the only way to find out whether a program is a good fit for your needs.
