(Reuters) - The city of San Francisco and nearby Santa Clara County sued President Donald Trump's administration on Tuesday, seeking to block a new rule that would drastically reduce legal immigration by denying visas to poor migrants.
Some experts say the new rule could cut legal immigration in half by denying visas and permanent residency to hundreds of thousands of people if they fail to meet high enough income standards or if they receive public assistance such as welfare, food stamps, public housing or Medicaid.
