When Indian Prime Minister Narendra Modi meets with President Donald Trump next week, increased U.S. restrictions on skilled immigrants visas will likely come up. However, the real migrant challenge — and opportunity — facing India comes from within its own borders. India’s internal migrant population has grown substantially in recent years, spurred by individuals moving from the country’s struggling north to the wealthier west and south. Central and state governments respond by either overlooking this trend, or trying to prevent it. Instead, they should understand how internal migration could vitally impact India’s economic trajectory, and that easing the transition for the millions who have already made the journey is the smart choice for India’s future.
