More Washington officials are headed to Texas this week as the immigration crisis worsens.

The city of McAllen, TX will be in the spotlight today as Department of Homeland Security Jeh Johnson will be in town to look at the facility there. McAllen Mayor Jim Darling telling ABC's 'This Week" what he'll see won't be pretty.

“They only have the clothes that are on their back. They haven’t had proper hygiene for the last couple of weeks,” Darling said.

Darling said the city is doing what they can to deal with something he won’t call a crisis yet.

There are a lot of little kids,” Darling said. “And so what happened to us is a Catholic church at the city of McAllen, [in addition to] other community entities got together and decided that we’re not going to send them from our city in those conditions. And they’re providing for all those needed services.”

Houston area Congressman Mike McCaul will hold a field hearing in McAllen on Thursday that Governor Rick Perry will testify at. And Dallas County could house up to 2,000 illegal immigrant children currently being held by DHS at the border for up to 120 days.

In the meantime, a new study has found that almost all of the job growth in the U.S, since 2000 has gone to both legal and illegal immigrants. Houston immigration lawyer Jacob Monty told KTRH why we're seeing that.

“We are not graduating enough STEM students and we are relying on foreign workers to meet those needs,” Monty said. “We have a labor shortage. We do not have enough of these workers.”
