Day Without Immigrants 2017 Day Without Immigrants (or A Day Without Immigrants) was a protest and boycott that took place on February 16, 2017, to demonstrate the importance of immigration, and to protest President Donald Trump's plans to build a border wall and to potentially deport millions of illegal immigrants. The strike called for immigrants not to go to work, to avoid spending money, and keep children home from school. People took part to show the importance of immigrants to the economy and also to protest possible racial profiling of U.S. citizens by immigration enforcement. The strike was planned on social media. People first started talking about the strike after the Women's March, and as the idea gained momentum, important people in the restaurant industry helped boost exposure.

As of January 2009, U.S. Customs and Border Protection reported that it had more than 580 mi of barriers in place. The total length of the continental border is 1,989 mi .

Boundary Treaty of 1970 The 1970 Boundary Treaty between the United States and Mexico settled all then pending boundary disputes and uncertainties related to the Rio Grande (Río Bravo del Norte) border. The most significant dispute remaining after the Chamizal Settlement in 1963 involved the location of the boundary in the area of Presidio, Texas, and Ojinaga, Chihuahua. The river channel was jointly relocated to approximate conditions existing prior to the dispute which arose from changes in the course of the river in 1907. The International Boundary and Water Commission was charged with its implementation. The American-Mexican Treaty Act of October 25, 1972 authorized the United States Section's participation. The project was undertaken in 1975 and completed in 1977.

Shark barrier A shark barrier (otherwise known as a "shark-proof enclosure" or "beach enclosure") is seabed-to-surface protective barrier that is placed around a beach to protect people from shark attacks. Often confused with shark nets, shark barriers form a fully enclosed swimming area that prevents sharks from entering (nets aim to reduce shark populations). Shark barrier design has evolved from rudimentary fencing materials to netted structures held in place with buoys and anchors. Recent designs have used plastics to increase strength, versatility and to reduce the environmental damage of bycatch.

Wall box Wall boxes are a type of post box or letter box found in many countries including France, the United Kingdom, the Commonwealth of Nations, Crown dependencies and Ireland. They differ from pillar boxes in that, instead of being a free-standing structure, they are generally set into a wall (hence the name) or supported on a free-standing pole, girder or other stable structure. In the UK, UK Dependent Territories, Colonies and former Colonies and in many former British Empire countries, wall boxes usually bear the initials of the reigning monarch at the time the box was made. The first UK wall boxes were erected in 1857 in Shrewsbury and Market Drayton.

Fort Covington–Dundee Border Crossing Fort Covington-Dundee is a border crossing connecting Sainte-Agnès-de-Dundee, Quebec, in Canada to Fort Covington, New York, on the Canada–United States border. It can be reached by Quebec Route 132 on the Canadian side and by Dundee Road on the American side.

Suicide barrier A suicide barrier is a barrier on a bridge (often a so-called suicide bridge known for suicide attempts), observation deck or other structure designed to prevent people from attempting suicide by deliberately jumping. Many suicide barriers are tall and fence-like. But suicide nets, which extend horizontally below the bridge and preserve views outward, have been used on the Bern Muenster Terrace in Bern, Switzerland and the Cornell University campus in Ithaca, New York. In 2009 a barrier was built for the Humber Bridge, and in April 2017, California began construction on a $200 million mesh barrier beneath the Golden Gate Bridge.

Fortifications of the inner German border The fortifications of the inner German border comprised a complex system of interlocking fortifications and security zones 1381 km long and several kilometres deep, running from the Baltic Sea to Czechoslovakia. The outer fences and walls were the most familiar and visible aspect of the system for Western visitors to the border zone, but they were merely the final obstacle for a would-be escapee from East Germany. The complexity of the border system increased steadily until it reached its full extent in the early 1980s. The following description and the accompanying diagram describe the border as it was around 1980.
