             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.—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.—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.—Research supported by this activity aims to increase U.S. engineering capability and strength, and focus that capability
                and strength on areas that are relevant to national problems and long-term needs. This activity also includes small business
                innovation research.

             Geosciences.—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.—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.—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.—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.—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.—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 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.
