Roughly half of STEM PhD students in the U.S. are international students. 75% of them stay in the U.S. long term after graduating to contribute their skills to U.S. scientific research and development. Cutting international student visas hurts U.S. science now and long into the future.

Fig. 1.Gas exchange and chlorophyll fluorescence from survey measurement.

Shaded regions represent developmental stages (gray=vegetative stage, red=flowering stage, blue=senescence stage). Bars on the circles represent the SEM.
