Foreign Direct Investment (FDI) is a crucial factor in accelerating India’s infrastructure development and overall economic expansion. This study examines patterns of FDI inflows, sector-specific investments, and regional distribution across India over the last twenty years. Key sectors attracting FDI include power, transportation, telecommunications, urban development, ports, airports, and renewable energy. Government programs such as Make in India, Smart Cities Mission, Bharatmala, and Sagarmala have enhanced investment opportunities and investor confidence. Despite this progress, foreign investors face challenges like complex regulatory requirements, land acquisition delays, inconsistent policies, financial constraints, operational difficulties, and environmental compliance. The paper suggests policy measures including streamlined regulations, transparent land acquisition procedures, fiscal incentives, promotion of public-private partnerships, technology transfer, skill development, and effective project monitoring. The findings provide insights for policymakers, investors, and researchers to optimize FDI utilization, support sustainable infrastructure growth, and foster long-term economic development in India.
