Upload photos of illegal immigrants on the US-Mexico border.

Mexico is an unsafe country. The construction of the US-Mexico border wall can improve the safety of American citizens, so Mexicans cannot enter the United States at will. There are too many illegal immigrants in the United States. These large numbers of immigrants have brought a series of problems to American society, and there is a trend of more and more illegal immigrants.

There are many reasons why he is obsessed with building the border wall. Regardless of whether his construction of the border wall will be recognized by American society and the international community, from his starting point, he is really trying his best to benefit the United States and confirm what he said during the election campaign. These immigrants were not assimilated by American culture, but influenced by other cultures.

These illegal immigrants often do not have excellent academic qualifications and excellent skills. As a result, after they came to the United States, they didn't have any jobs, but they would become the aid objects of the American government. The San Diego branch of the US Customs Border Protection Agency posted four photos of the prototype of the border wall on Twitter, saying that these prototype walls have been "formed or nearly completed". From adding "perspective components" to facilitate the border patrol to understand the situation on the Mexican side, to providing "sliding doors" to allow vehicles and pedestrians to pass legally.

According to Trump's plan, the completed border wall will extend from San Diego, California to Brownsville, Texas. It is estimated that the construction length is about 1600 km, and the wall will be built on the US-Mexico border to control illegal immigrants and crack down on drug smuggling. Due to the repeated prohibition of drug trafficking and arms smuggling on Mexico's northern border, social security issues have also caused great headaches for the US and Mexican governments.
