The border between the US and Mexico spans about 1,900 miles, of which nearly 700 miles are currently covered by walls and fences. Tijuana is the largest city in Baja California, one of the six Mexican states with a border to the US.

The residents of this house near the US-Mexico border fence enjoy a wider view of the scrublands in the US state of California.

Mexican architect Carlos Torres, 68, has been living in his house near the fence for three decades. He said the proposed wall will not be able to halt immigration. "Trump doesn't know what he's talking about. Here at this fence, people keep crossing every week," Torres explained.

Guatemalan chef Joaquin, 36, builds a bed in a tree, near a section of the border fence. He said he was deported from the United States. At night from his bed, Joaquin tries to look into the heavens through the leaves. "I've tried to cross so many times that the border guards even got to know me, but I never made it back," he said.

A house stands near the US-Mexico fence on the outskirts of Tijuana. Last month, the US authorities posted a call for proposals to expand existing walls along the Mexican border. The US president Donald Trump talked about building a wall several times during his election campaign. This project is being seen as Trump’s flagship anti-immigration project.

The roof of a house made with an advertisement banner is seen next to the fence, extension of which may cost between $12 billion (11.3 billion euros) and $15 billion.

This shack standing next to the US-Mexico fence may look as if it can be climbed easily, but the proposed wall is going to be harder to cross. Because according to the tender, the wall should not be scalable, even using sophisticated climbing aids, and should be sunk at least six feet into the ground to avoid tunneling.

A girl runs outside her home near the US-Mexico fence, which was made of corrugated metal. However, the proposed wall will be of two different kinds of material - solid concrete and a transparent one.
