         The Research and Related Activities appropriation enables the United States to provide leadership and promote progress across
            the expanding frontiers of scientific and engineering research and education.
         
         The major research program activities of NSF are:
         Biological Sciences.âThis activity supports understanding how complex living systems function and interact with each other and with non-living
            systems, which has direct impacts on issues related to the economy, food, human welfare, and the environment. Research in
            this activity crosses scales from molecules to cells through organisms to ecosystems. This activity's investment portfolio
            includes projects on understanding the fundamental characteristics of biological energy systems, the changing dynamics of
            the biosphere, and infrastructure and research resources such as databases, research centers, and observatories, and efforts
            to broaden participation and develop the next generation of biological researchers.
         
         Computer and Information Science and Engineering.âThis activity promotes the progress of computer and information science and engineering research and education, and advances
            the development and use of cyberinfrastructure across the science and engineering research enterprise; promotes understanding
            of the principles and uses of computing and information technology in society; and contributes to universal, transparent,
            and affordable participation in a knowledge-based society.
         
         Engineering.âResearch supported by this activity aims to increase and strengthen U.S. engineering capability and focus that capability
            on areas that are relevant to national problems and long-term needs. This activity also includes small business innovation
            research.
         
         Geosciences.âThis activity supports research and associated infrastructure to advance knowledge of the properties and dynamics of the
            planet on which we live. Research includes understanding the causes and implications of earth system dynamics, as well as
            disruptive processes such as earthquakes and storms.
         
         Mathematical and Physical Sciences.âResearch in this activity is directed at increasing understanding of natural laws and phenomena across the astronomical
            sciences, chemistry, materials sciences, mathematical sciences, and physics. Research support is available in multiple modalities
            ranging from multi-user facilities and mid-scale instrumentation to individual investigator awards, from sites for undergraduate
            research experiences to early career faculty development and collaborative and international efforts.
         
         Social, Behavioral, and Economic Sciences.âThis activity supports research, education, and infrastructure in the social, behavioral, cognitive, and economic sciences
            and funds the collection and dissemination of statistics on the science and engineering enterprise.
         
         Office of International Science and Engineering (OISE).âThis activity serves as the focal point of international activities at NSF. In addition to strategic funding and co-funding
            that targets catalytic partnerships and workforce-building international research opportunities, OISE advances NSF's global
            science leadership through extensive interactions with U.S. and global counterpart agencies and organizations.
         
         Office of Polar Programs.âThis activity supports Arctic and Antarctic research and operational science support and other related activities for United
            States polar research programs, including the funding to reimburse Federal agencies for logistical and other related activities
            supported by the United States Antarctic Program.
         
         Integrative Activities.âThis activity supports emerging cross disciplinary research efforts, as well as major research instrumentation and Mid-scale
            research infrastructure. This activity also provides support for the Science and Technology Policy Institute. The Established
            Program to Stimulate Competitive Research broadens participation of States and regions in science and engineering by helping
            institutions expand their research capacity and competitiveness.
         
         The United States Arctic Research Commission (USARC) is an independent agency, funded through NSF's appropriations. USARC promotes Arctic research and recommends national Arctic
            research policies to guide Federal agencies in developing and implementing their research programs in the Arctic region.

         The Education and Human Resources (EHR) appropriation funds and manages a comprehensive set of programs that further NSF's
            goals of ensuring a diverse, globally competitive U.S. science, technology, engineering, and mathematics (STEM) workforce,
            as well as a scientifically literate population. To advance those goals, EHR collaborates with other NSF research units and
            Federal agencies, and promotes public-private partnerships. EHR supports research on STEM teaching and learning to provide
            the evidence base for improvements in education at all levels in the STEM disciplines. Supporting development and effective
            implementation of new learning technologies is also a priority. EHR's pre-K-12 education-research programs, for example, develop
            and test new instruction materials for students and teachers, which incorporate the latest advances in teaching, learning,
            and education technologies. STEM teacher-education opportunities occur throughout the full continuum, from pre-service and
            in-service, through life-long learning. Research programs at the undergraduate level improve curricula, strengthen laboratory
            courses, enhance faculty effectiveness, and lead education reforms in STEM disciplines. Advanced technological education programs
            strengthen student preparation for the high-technology workforce. Support of graduate-level STEM education primarily includes
            fellowships and traineeships to sustain U.S. leadership in global science and technology. All EHR programs aim to broaden
            participation of groups underrepresented in STEM fields by, for example, improving infrastructure and academic programs at
            minority-serving institutions. EHR activities also include programs supported by H-1B non-immigrant visa fees, which provide
            undergraduate and graduate scholarships in STEM disciplines, improve educational opportunities for students, and provide research
            opportunities for STEM teachers and students.

         The Budget proposes authorizing legislation to double the American Competitiveness and Workforce Improvement Act (ACWIA) fee
            for the H-1B visa program in order to help train American workers and close the skills gap.  The proposal would increase the
            ACWIA fee to $3,000 per worker for large employers and $1,500 per worker for small employers.  The increased revenue would
            provide additional funding for Department of Labor (DOL) job training grants to support apprenticeship.  Under the proposal,
            the allocations for DOL job training grants (50 percent); DOL foreign labor certifications (5 percent); National Science Foundation
            (NSF) Innovative Technology Experiences for Students and Teachers program (10 percent); and DHS processing costs (5 percent)
            would remain the same.  The NSF allocation for STEM scholarships would decrease from 30 percent to 15 percent, which would
            maintain absolute funding levels under current estimates.  The proposal would initiate a new 15 percent allocation for the
            Department of Education's Career and Technical Education formula grant.

         This account consists of contributions from foreign governments, organizations, and individuals to fund various cooperative
            efforts in science, research, and education. These efforts include major international projects, such as operation of the
            Gemini telescopes, and the NSF ocean discovery program. Other smaller activities supported include cooperative research, joint
            seminars, exchange of senior scientists, short-term research development visits, international conferences, and support for
            certain special functions of NSF and the National Science Board. These funds are not otherwise available.
