A visa is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or leave its territory. Visas typically include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual can work in the country in question. Visas are associated with the request for permission to enter a territory and thus are, in most countries, distinct from actual formal permission for an alien to enter and remain in the country. In each instance, a visa is subject to entry permission by an immigration official at the time of actual entry and can be revoked at any time. Visa evidence most commonly takes the form of a sticker endorsed in the applicant's passport or other travel document but may also exist electronically. Some countries no longer issue physical visa evidence, instead recording details only in immigration databases.
The Visa Waiver Program (VWP) is a program of the United States federal government that allows nationals of specific countries to travel to the United States for tourism, business, or while in transit for up to 90 days without having to obtain a visa. It applies to all fifty U.S. states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, as well as to Guam and the Northern Mariana Islands, which also have an additional program with waivers for more nationalities; American Samoa has a similar but separate program.
In the United States, identity documents are typically the regional state-issued driver's license or identity card, while also the Social Security card and the United States Passport Card may serve as national identification. The United States passport itself also may serve as identification. There is, however, no official "national identity card" in the United States, in the sense that there is no federal agency with nationwide jurisdiction that directly issues an identity document to all US citizens for mandatory regular use.
TN status is a special non-immigrant classification of foreign nationals in the United States, which offers expedited work authorization to a citizen of Canada or a national of Mexico. It was created as a result of provisions of the North American Free Trade Agreement that mandated simplified entry and employment permission for certain professionals from each of the three NAFTA member states in the other member states. The provisions of NAFTA relevant to TN status were then carried over almost verbatim to the United States–Mexico–Canada Agreement that replaced NAFTA in 2020.
United States passports are passports issued to citizens and nationals of the United States of America. They are issued exclusively by the U.S. Department of State. Besides passports, limited-use passport cards are issued subject to the same requirements. It is unlawful for US citizens and nationals to enter or exit the country without a valid US passport or passport-replacement document compliant with the Western Hemisphere Travel Initiative, though there are many exceptions; waivers are generally granted for U.S. citizens returning without a passport, and the exit requirement is not enforced. As of December 2023, a United States passport allows visa-free travel to 186 countries and territories, being ranked as the seventh most powerful in the world in terms of travel freedom.
The Permanent Resident card also known colloquially as the PR Card or the Maple Leaf card, is an identification document and a travel document for permanent residents of Canada. It is one of the methods by which Canadian permanent residents can prove their status and is, along with the permanent resident travel document (PRTD), one of the only documents that allow permanent residents to return to Canada by a commercial carrier.
A Canadian passport is the passport issued to citizens of Canada. It enables the bearer to enter or re-enter Canada freely; travel to and from other countries in accordance with visa requirements; facilitates the process of securing assistance from Canadian consular officials abroad, if necessary; and requests protection for the bearer while abroad.
Visitors to the United States must obtain a visa from one of the U.S. diplomatic missions unless they are citizens of one of the visa-exempt or Visa Waiver Program countries.
The Office of Field Operations (OFO) is a federal law enforcement agency within the U.S. Customs and Border Protection (CBP) responsible for managing United States customs operations at 20 Field Operations offices, 328 ports of entry, and 16 pre-clearance stations in Canada, Ireland, the UAE, and the Caribbean. Headed by an Executive Assistant Commissioner, OFO directs the activities of more than 27,000 employees, including more than 22,000 CBP Officers and Agriculture Specialists.

NEXUS is a joint Canada Border Services Agency and U.S. Customs and Border Protection-operated Trusted Traveler and expedited border control program designed for pre-approved, low-risk travelers. Members of the program can avoid waits at border entry points by using reserved lanes at land crossings into Canada and the United States, by using self-serve kiosks at airports in Canada, the US and some international locations, or by phoning border officials for a marine entry. A NEXUS membership card is a valid document under the Western Hemisphere Travel Initiative (WHTI), so it can be used in place of a passport, including by air if flying between the US and Canada. However, carrying a valid passport is still recommended, in the rare event that a flight is diverted to an airport without NEXUS support.
A travel document is an identity document issued by a government or international entity pursuant to international agreements to enable individuals to clear border control measures. Travel documents usually assure other governments that the bearer may return to the issuing country, and are often issued in booklet form to allow other governments to place visas as well as entry and exit stamps into them.
The United States passport card is an optional national identity card and a travel document issued by the U.S. federal government in the size of a credit card. Like a U.S. passport book, the passport card is only issued to U.S. citizens and U.S. nationals exclusively by the U.S. Department of State. The passport card allows its holders to travel by domestic air flights within the U.S., and to travel by land and sea within North America. However, the passport card cannot be used for international air travel. US passport cards are used to verify identity and US citizenship. The requirements to attain the passport card are identical to the passport book and compliant to the standards for identity documents set by the REAL ID Act.
An Estonian passport is an international travel document issued to citizens of Estonia, and may also serve as proof of Estonian citizenship. Besides enabling the bearer to travel internationally and serving as indication of Estonian citizenship, the passport facilitates the process of securing assistance from Estonian consular officials abroad or other European Union member states in case an Estonian consular is absent, if needed. If an Estonian citizen wishes to receive an identity document, especially an Estonian passport, somewhere other than the foreign representation of the Republic of Estonia, then the bearer of the Estonian citizenship staying abroad could receive the travel documents in embassies of any EU country worldwide by paying 50 Euro. Many countries require passport validity of no less than 6 months and one or two blank pages.
A B visa is one of a category of non-immigrant visas issued by the United States government to foreign nationals seeking entry for a temporary period. The two types of B visa are the B-1 visa, issued to those seeking entry for business purposes, and the B-2 visa, issued to those seeking entry for tourism or other non-business purposes. In practice, the two visa categories are usually combined and issued as a "B-1/B-2 visa" valid for a temporary visit for either business or pleasure, or a combination of the two. Nationals of certain countries do not usually need to obtain a visa for these purposes.
Global Entry is a program of the U.S. Customs and Border Protection service that allows pre-approved, low-risk travelers to receive expedited clearance upon arrival into the United States through automatic kiosks at select airports and via the SENTRI and NEXUS lanes by land and sea. As of May 4, 2018, Global Entry was available at 53 U.S. airports and 15 preclearance locations. By April 2018 more than five million people were enrolled in Global Entry and approximately 50,000 new applications for the program were being filed each month.
U.S. citizens and permanent residents entering Canada by land are required to possess the requisite documentation, such as a passport, driver's license, and other valid identification documents. They must also meet other criteria, such as passing security measures, before they are allowed entry into Canada. Consequently, travelers must also meet the requirements for re-entering the U.S. at the end of their visit.
The visa policy of Canada requires that any foreign citizen wishing to enter Canada must obtain a temporary resident visa from one of the Canadian diplomatic missions unless they hold a passport issued by one of the 53 eligible visa-exempt countries and territories or proof of permanent residence in Canada or the United States.
