If you already have a Master of Business Administration (MBA) and want to return to school to obtain a Registered Nurse (RN) license, the student loans you may need to take out would likely be considered
undergraduate loans. This is because nursing programs are typically considered undergraduate-level education, even if you already hold a higher degree in another field.
You should check with the financial aid office of the nursing school you plan to attend to confirm the type of loans that would be available to you. They will be able to provide you with specific information about the financial aid options that are available to students in your situation.
