Tens of thousands of children crossing into the US from Central American nations have overwhelmed the Government's ability to respond, senior officials have said.
US President Barack Obama has urged Congress to move swiftly to approve an emergency spending request for the crisis.
ITV News Washington Correspondent Robert Moore reports:
The children come mainly from Guatamala, Honduras and El Salvador, and the numbers heading north through Mexico, and into Texas are rising dramatically.
Brandon, 14, crossed the Rio Grande from Guatamala on a small, leaking raft to make it to the US.
He told ITV News' Robert Moore, "I was terrified. People said if I fell into the river I would die."
More than 52,000 unaccompanied minors from the three countries have been caught trying to sneak over the border since October, double the number from the same period the year before.
