The number of migrants apprehended at the southern border dropped again to reach 36,300 in October, marking the fifth straight month they declined, according to the Wall Street Journal, Nov. 10.

“The decline in border apprehensions, which have decreased by about 75% since their height of 132,856 in May, and 10% in the last month alone, appears to be due to more than typical seasonal fluctuations and suggests that President Donald Trump’s immigration policies are having their intended effect,” Vox wrote on Nov. 11.

While the first phase of the new border wall of President Trump is being constructed on the southern border, it has proven to be the least effective of its measures in keeping migrants out, who have recently cut through the existing barrier with commercial saws.

Alternatively, officials attributed the drop in border apprehensions to other policies of President Trump: involving several Central American nations in U.S. immigration enforcement efforts to stop people from moving from the “Northern Triangle” of Central America — Guatemala, Honduras, and El Salvador — to the southern border of the United States.

Taken together, these policies created a series of barriers for asylum seekers.

Acting U.S. Customs and Border Protection Commissioner Mark Morgan also told reporters last month that the decline in border apprehensions can be attributed to the partnerships the U.S. has pursued with Central American countries to stop migrants before they reach the U.S. border.

The “Remain in Mexico” policy of President Trump requires that asylum seekers who may have been able to remain in the United States under previous administrations until their asylum claims have been adjudicated, are now turned back to Mexico to face asylum proceedings on the other side of the border.

Most Central American asylum seekers either accept a temporary work visa or refugee status deals from Mexico, or return to their home countries.

Around 55,000 migrants have been turned away under the “Remain in Mexico” policy.

The Administration of President Trump has also put pressure on the Mexican government to step up its own border control and increase efforts to capture and deport illegal immigrants in Mexico before they enter the United States.

“After Trump threatened to impose tariffs on all Mexican goods in June, the Mexican government deployed a record 15,000 troops to detain over 31,000 migrants that month and almost 19,000 in July,” Vox reported.

Mark Morgan has praised Trump’s policies as “unilateral” and “unprecedented. He said: “This administration’s strategies have brought about results — dramatic results. While Congress has failed to put forth a single piece of legislation – even being able to introduce it to the floor to address this crisis – we have addressed this crisis.”
