Outgoing California Rep. Anna Eshoo’s biggest tech regret isn’t what you’d expect: It’s immigration reform.

“We would not be the nation that we are without being an immigrant nation. And immigrants play a very important role in the technology industry. So many come to the United States to be educated here,” Eshoo, whose district covers Silicon Valley, said Sunday during an interview on MSNBC’s “Inside with Jen Psaki.”

“We have the finest colleges and universities,” Eshoo continued. “Certainly, Stanford University, which is the geographic center of my district. But once they’re educated, if they cannot get a green card, they have to leave.”
