The Trump administration's recent immigration policy has sparked significant concern among leaders in the US tech sector, particularly regarding its potential impact on innovation. Founders of LinkedIn and Coursera, Reid Hoffman and Andrew Ng, have publicly criticized the new rule, which mandates that many foreigners currently in the US must leave to apply for permanent residency from their home countries. Hoffman expressed worries about the implications for AI researchers and students, while Ng labeled the policy a 'capricious attack on legal immigration,' warning it could diminish the pool of doctors, teachers, and scientists in the US. YCombinator CEO Garry Tan also condemned the policy, stating that retaining skilled individuals is crucial for building future businesses. The USCIS memo emphasizes that obtaining a green card is a discretionary benefit, signaling a tougher stance on immigration for those seeking long-term residency. Experts note that this move aligns with a broader trend of increasing scrutiny and restrictions on immigration pathways for skilled workers, raising fears about the future of US competitiveness in technology and innovation.
