At least 3,000 US forces will remain guarding the border crossing during the year-end festivities.
US forces stationed on the border with Mexico will begin departing during the week, but some 3,000 troops will remain there during the end of the year festivities, government officials said.
About 4 thousand 500 troops have been in the border for several weeks, where they install wire fences and protect the border patrol agents in California, Arizona and Texas.
President Donald Trump sent the troops in response to a caravan of Central American migrants who were approaching the border. The number of migrants has decreased and fences are installed to a large extent.
Officials said the need for combat engineers and transport helicopter crews has decreased. But many members of the military police will remain at the border.
Officials spoke on condition of anonymity because they were not authorized to report publicly.
