New Delhi:The Trump administration is preparing a fresh set of immigration rules that could make it more difficult for foreign professionals, students and employers to navigate the US immigration system. The proposed changes cover some of the most popular routes used by Indians to study and work in the United States. Therefore, Indians, who form one of the largest immigrant groups in the US, could especially face more hurdles under proposed changes to the H1B programme, L1 visas and student visas. The proposals are part of the latest Unified Regulatory Agendas released by the US Departments of Homeland Security (DHS), Labor (DOL) and State (DOS). While none of the measures has taken effect yet, they offer the clearest indication of the administration’s plans.
