President Barack Obama plans to make life a little easier for some foreign tech workers, but Silicon Valley representatives are disappointed that his immigration rule changes will not satisfy long-standing demands for more visas and faster green cards.

In a speech Thursday, Obama outlined plans to use his executive authority to help millions of undocumented people. He also announced minor adjustments to cut through red tape for visa holders and their families, including letting the spouses of certain H-1B visa holders get work permits.

"I will make it easier and faster for high-skilled immigrants, graduates and entrepreneurs to stay and contribute to our economy, as so many business leaders have proposed," Obama said.
