VIDEO: Migrants from Texas arrive in Chicago

(NBC) - Buses pulled into Chicago's Union Station last night to drop off 75 migrants from the US border with Mexico.

This is the just latest chapter of the bitter political battle over the Biden administration's immigration policy.

Texas Governor Greg Abbott has been sending migrants to so-called "sanctuary cities" since April.

Chicago Mayor Lori Lightfoot said the city welcomes the migrants.

She also slammed Abbotts' actions.

For some migrants, this is a chance to start a new life

CNBC's Perry Russom spoke to a father who walked for two months from Venezuela to the U.S. border.

In the crowd of migrants bussed to Chicago, 3-year-old Cataleya is the youngest.

Her fascination with a watch covers the exhaustion of her two month journey from Venezuela.

Her father, Elier lists the countries they walked through to reach the American border.

From Venezuela they went to Columbia, then Panama, Costa Rica, Nicaragua, Honduras, Guatemala and Mexico.

A continent crossing journey wearing down the feet of his pregnant wife, Cataleya wants to show us the bottom of her feet too.

We ask Elier, 'Why America?'

It is simply a country that offers many life opportunities he says.

Elier tells us in Venezuela there is no food, no work and the country is in political crisis.

The UN Refugee Agency reports there are more than 6 million Venezuelan refugees and migrants globally making it the second largest external displacement crisis in the world.

A spokesperson for Texas Governor Greg Abbott compares the bracelets to a plane ticket.

Elier carries a clear bag, holding his family's documents, donated diapers and a t-shirt.

There are MRE's, meals ready to eat and medication for his wife.

A Chicago Police officer tells us there was no heads up the migrants were being sent here.

Baltazar Enriquez shows up to help in his pajamas - buy the group hamburgers.

"We're ready. We've been ready for this." says Little Village Community Council Baltazar Enriquez.

Enriquez is with Little Village Community Council in Chicago.

The group started in the 60s primarily helping Czechoslovakia immigrants - now helping migrants from Latin-American and South American countries.

"I know the pain. I know the suffering of coming to a country where you don't the language. You don't know the culture. You don't know anything and It's a culture shock to see this big building. All this traffic. A lot of them come form rural areas. They've never seen a big building like this." Enriquez said.

There is hope in their tired eyes.

They have a meal and another bus ride to a shelter.

A temporary home in a country where they want to stay forever.
