-Emir Mesa spends most of her days in the kitchen at the Juventud Dos Mil shelter.

She makes meals for about 130 migrants waiting here on the edge of Mexico, a stone's throw from the border with the United States.

Emir has a brand-new baby granddaughter, Haniqua, not yet a month old.

She says the baby's name means rain.

-We want to do things the right way.

We don't want to enter as illegals, and for this reason, we're here in Tijuana waiting to enter the right way, not to enter as contraband, not to enter as illegal.

-Immigrant advocates on both sides of the border are bracing for a second Trump administration.

The president-elect is promising to close the border for people like Emir and her family.

He's also said he'll conduct the largest mass deportation campaign in US history, and he's threatened tariffs on Mexico if the country doesn't stop the northbound flow of migrants and Fentanyl.

-What was our reaction?

Sadness.

Why?

Because many people have been saying they're going to close the doors.

-Jose Maria Garcia, the director of Juventud Dos Mil, said there's a mood of fear, anxiety, and uncertainty at the border after Trump's win.

-He's been very clear, this man, this Mr. Trump, in saying that he's going to get rid of this program.

You're going to see stronger and more massive deportations.

We'll see what's going to happen to us as organizations here in the north of the country.

-Nowhere could Trump's new border policies have more impact than in California.

There are about 1.8 million undocumented Californians living in the state, according to the Pew Research Center.
