Reforming Immigration Law to Allow More Foreign Student Entrepreneurs to Launch Job-Creating Ventures in the United States

As universities move toward a more experiential approach to entrepreneurship education, many academic units and cross-campus entrepreneurship programs are encouraging their students to actively engage with the curriculum and apply the skills they learn. One such approach is to have students start their own businesses before they graduate. In addition to enhancing their education, participation in the planning, launch and operation of a start-up venture can lead directly to the creation of new jobs for many other individuals. Unfortunately, being the founder of a start-up venture in the United States proves complicated for foreign students in our colleges and universities. Across the country, both undergraduate and graduate entrepreneurship students desiring to participate actively in a startup face vexing immigration law challenges. This paper outlines some of the barriers that foreign student entrepreneurs face, and describes how bipartisan legislation would help to address some of these roadblocks

Weak Lensing by High-Redshift Clusters of Galaxies II: Mean Redshift of the Faint Background Galaxy Population

We use weak lensing shear measurements of six z>0.5 clusters of galaxies to derive the mean lensing redshift of the background galaxies used to measure the shear. Five of these clusters are compared to X-ray mass models and verify a mean lensing redshift for a 23<R<26.3, R-I<0.9 background galaxy population in good agreement with photometric redshift surveys of the HDF-S. The lensing strength of the six clusters is also analyzed as a function of the magnitude of the background galaxies, and an increase in shear with increasing magnitude is detected at moderate significance. The change in the strength of the shear is presumed to be caused by an increase in the mean redshift of the background galaxies with increasing magnitude, and the degree of change detected is also in agreement with those in photometric redshift surveys of the HDF-S.Comment: 6 pages, 4 figures, accepted by A&
