Governor Jerry Brown has wrapped up his trip to Mexico and should be back across state lines sometime this evening.
Before departing, he signed another memorandum on the protection of migrant workers in the state.
It followed an earlier agreement to reduce greenhouse gases and a pact on university transfers.
Front page on the papers in Mexico City were Brown's comments on immigration.
He told reporters last night "whatever can be done by a mere governor" to shelter unaccompanied children, "will be done."
Brown had said little on the issue before his trip this week.
He pledged funds for new shelters in the state and called for further investment in Latin America.
