From John Hopkins University: "STEM is a 17-month extension offered to F-1 status holders who have completed their initial OPT and possess degree in Science, Technology, Engineering and Mathematics (STEM) as designated by the Department of Homeland Security. STEM extensions are not available to BSN holders because the field of nursing is not
on the STEM list. Moreover, since the field of study and the field of work must be directly related, STEM extensions will not be available to BSN graduates on OPT."

Biological Sciences is not nursing, it refers to biology, microbiology, molecular biology, physiology. Physical Sciences refers to earth science, geology, physics, sometimes physical chemistry, and the like. Nursing definitely does not fall under physcial sciences, most nursing majors aren't even required to take a physical science course as part of their major. I'm sorry but I don't think you'll convince your office of international studies or USCIS that nursing falls under one of the STEM categories.
