Second wave of 30,000 undocumented children expected to cross border

Posted: Updated:

A second wave of about 30,000 unaccompanied minors is expected to cross the U.S. Mexico border in September and October, according to the U.S. Committee for Refugees and Immigrants.

Right now, immigrant experts say it's just too hot for them to cross.

So far, 62,000 undocumented children have arrived over a six-month period.

Most of them are women and children fleeing violence from their Central American countries.

Many arrived by bus or by air to Arizona from Texas because Texas couldn't handle the surge of people.
