International border in the context of "Border checkpoint"

In international law, a stateless person is someone who is "not considered as a national by any state under the operation of its law". Some stateless people are also refugees. However, not all refugees are stateless, and many people who are stateless have never crossed an international border. At the end of 2022, the United Nations High Commissioner for Refugees published an estimation of 4.4 million people worldwide as either stateless or of undetermined nationality, 90,800 (+2%) more than at the end of 2021. However, the data itself is not complete because UNHCR does not have data from many countries, such as from at least 22 countries where mass statelessness exists. The data also does not include de facto stateless people who have no legal identification to prove their nationality or legal existence. According to the World Bank, at least 850 million fit that category.

The status of a person who might be stateless ultimately depends on the viewpoint of the state with respect to the individual or a group of people. In some cases, the state makes its view clear and explicit; in others, its viewpoint is harder to discern. In those cases, one may need to rely on prima facie evidence of the view of the state, which in turn may give rise to a presumption of statelessness.

The international border between the modern states of France and Germany has a length of 450 km (280 mi). The southern portion of the border, between Saint-Louis at the border with Switzerland and Lauterbourg, follows the River Rhine (Upper Rhine) in a south-to-north direction through the Upper Rhine Plain. The border then turns westward until it reaches the tripoint between France, Germany and Luxembourg.

The Germany–Poland border (German: Grenze zwischen Deutschland und Polen, Polish: Granica polsko-niemiecka) is the state border between Poland and Germany, mostly along the Oder–Neisse line, with a total length of 467 km (290 mi). It stretches from the Baltic Sea in the north to the Czech Republic in the south.

The international border between Finland and Russia is 1,340 km (830 mi) long and runs approximately north to south, mostly through taiga forests and sparsely populated rural areas. It does not follow any natural landmarks, such as mountains or rivers. It is also an external border of the European Union and NATO.

It is patrolled by the Finnish Border Guard and the Border Guard Service of Russia, who also enforce border zones extending, respectively, up to 3 km (1.9 mi) on the Finnish side and at least 7.5 km (4.7 mi) on the Russian side. A permit is required for entry to these border zones. Electronic surveillance on the Finnish side is concentrated most heavily on the southernmost 200 kilometers (125 miles). In addition, the Finnish Border Guard conducts irregularly scheduled dog patrols multiple times daily to catch illegal entries into the border zone. In the Arctic region, Russia maintains its 500-year-old border patrol, with plans to upgrade Soviet-era technologies to reduce costs and improve efficiency by 2020.

Nuevo León, officially the Free and Sovereign State of Nuevo León, is a state in northeastern Mexico. The state borders the Mexican states of Tamaulipas, Coahuila, Zacatecas, and San Luis Potosi, and has an extremely narrow international border with the U.S. state of Texas. Covering 64,156 square kilometers (24,771 square miles) and with a population of 5.78 million people, Nuevo León is the thirteenth-largest federal entity by area and the seventh-most populous as of 2020.

Monterrey, the state's capital, is the most populous city in Nuevo León and the ninth-largest in Mexico. Monterrey is part of the Monterrey metropolitan area, the second-largest metropolitan area in the country with an estimated population of 5.3 million people in 2020. About 92% of the state's population lives in the metropolitan area.

Far North Queensland (FNQ) is the northernmost part of the Australian state of Queensland (QLD). Its largest city is Cairns and it is dominated geographically by Cape York Peninsula, which stretches north to the Torres Strait, and west to the Gulf Country. The waters of Torres Strait include the only international border in the area contiguous with the Australian mainland, between Australia and Papua New Guinea.

The region is home to three World Heritage Sites, the Great Barrier Reef, the Wet Tropics of Queensland and Riversleigh, Australia's largest fossil mammal site. Far North Queensland lays claim to over 70 national parks, including Mount Bartle Frere; with a peak of 1,622 metres (5,322 ft) it is the highest peak in both Northern Australia and Queensland.

A separation barrier or separation wall is a barrier, wall or fence, constructed to limit the movement of people across a certain line or border, or to separate peoples or cultures. A separation barrier that runs along an internationally recognized border is known as a border barrier.

David Henley opines in The Guardian that separation barriers are being built at a record-rate around the world along borders and do not only surround dictatorships or pariah states. In 2014, The Washington Post listed notable 14 separation walls as of 2011, indicating that the total concurrent number of walls and barriers which separate countries and territories is 45.

Southeast Alaska, often abbreviated to southeast or southeastern, and sometimes called the Alaska(n) panhandle, is the southeastern portion of the U.S. state of Alaska, bordered to the east and north by the northern half of the Canadian province of British Columbia (and a small part of Yukon). The majority of southeast Alaska is situated in Tlingit Aaní, much of which is part of the Tongass National Forest, the United States' largest national forest. In many places, the international border runs along the crest of the Boundary Ranges of the Coast Mountains (see Alaska boundary dispute). The region is noted for its scenery and mild, rainy climate.
