When Barack Obama welcomes Manmohan Singh to the White House on Sept. 27, the Indian prime minister will voice his concerns over the US immigration bill.

It explicitly prohibits foreign direct investment (FDI) in e-commerce, though it’s opening up the market to foreign companies operating brick-and-mortar stores.
