An arrival card is a legal document used by a country's immigration authorities to provide passenger identification and a record of a person’s entry to a country. It also provides information on health and character requirements for non-citizens entering a particular country. Some countries like the United States and Singapore attach this card to a departure card where the latter is retained in the alien's passport until his eventual departure. The arrival card can also be combined with items found in a customs declaration card which some countries require incoming passengers to fill-out separately.

An arrival card may also be known as an incoming passenger card, landing card and disembarkation card.

The information requested varies by country. Typically the information requested on the departure card includes

Travelers are generally required to sign, date, and declare the information is true, correct, and complete.

Passengers on international flights are often required to complete the cards and are often required to present the cards and their passports at immigration checkpoints. Some countries, most notably those in the Schengen Zone don't require aliens to complete this card.

The Four Corners is a region of the United States consisting of the southwestern corner of Colorado, northwestern corner of New Mexico, northeastern corner of Arizona and southeastern corner of Utah. The Four Corners area is named after the quadripoint where the boundaries of the four states meet, where the Four Corners Monument is located. The majority of the Four Corners region is part of semi-autonomous indigenous American Indian nations, the largest of which is the Navajo Nation, followed by Hopi, Ute and Zuni Indian nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged and arid. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park and Canyon de Chelly National Monument. The most populous city in the Four Corners region is Farmington, New Mexico, followed by Durango, Colorado.

The United States first acquired the area now called Four Corners from Mexico after the Mexican–American War in 1848. In 1863 Congress created Arizona Territory from the western part of New Mexico Territory. The boundary was defined as a line running due south from the southwest corner of Colorado Territory, which had been created in 1861. This was an unusual act of Congress, which almost always defined the boundaries of new territories as lines of latitude or longitude, or following rivers. By defining one boundary as starting at the corner of another Congress ensured the eventual creation of four states meeting at a point, regardless of the inevitable errors of boundary surveying. The area was first surveyed by the U.S. Government in 1868 as part of an effort to make Colorado Territory into a state, the first of the Four Corners states formed. The first marker was placed at the spot in 1912. The first Navajo tribal government was established in 1923 to regulate an increasing number of oil exploration activities on Navajo tribal lands.
