US migrant crisis shifts from Texas to California's border with record surge in illegal crossings along the US-Mexico frontier.

The US migrant crisis is shifting from Texas to California's border, with a record surge of illegal crossings along the 1,950-mile US-Mexico frontier. The geography of the US migration problem is moving west to border states such as Arizona and California, as the crisis has predominantly centered on Texas. This follows a change in migrant flow, with numbers in California increasing compared to the 2,300 daily crossings in December.
