Maybe because the intended target are immigrants who purportedly put a higher load on welfare and public services:
> "The Trump administration is bringing an end to the abuse of America's immigration system by those who would extract wealth from the American people," State Department spokesman Tommy Pigott said. "Immigrant visa processing from these 75 countries will be paused while the State Department reassesses immigration processing procedures to prevent the entry of foreign nationals who would take welfare and public benefits," he said.
Since the Indian diaspora is famously known to be the wealthiest on average in the US, they wouldn't be targeted under such reasoning.
