A visa (short for the Latin carta visa, lit. "the document having been seen") is a document issued by a country giving a certain individual permission to formally request entrance to the country during a given period of time and for certain purposes (see below for caveats and exceptions). Most countries require possession of a valid visa as a condition of entry for foreigners, though there exist exemption schemes (see passport for examples of such schemes). Visas are typically stamped or attached into the recipient's passport, or are sometimes issued as separate pieces of paper.

Visas are associated with the request for permission to enter (or exit) a country, and are thus distinct from actual formal permission for an alien to enter and remain in the country. A visa does not guarantee admission into the country for which the alien has the visa. This formal permission is typically granted by stamping the visa and, in some cases, by providing an additional document as proof of status, such as the United States' I-94. The common phrase "he has to leave because his visa has expired" is thus, strictly speaking, incorrect: the visitor's status has expired, the visa may or may not have.
Some countries, such as some states of the former Soviet Union, require that their citizens, and sometimes foreign travelers, obtain an exit visa in order to be allowed to leave the country. Until 2004, foreign students in Russia were issued only an entry visa on being accepted to University there, and had to obtain an exit visa to return home. This policy has since been changed, and foreign students are now issued multiple entry (and exit) visas. Citizens of the People's Republic of China who are residents of the mainland are required to apply for special permits in order to leave the mainland, including to enter the Special Administrative Regions of Hong Kong and Macao (and SAR residents require a Home Return Permit to visit the mainland). Saudi Arabia requires all resident foreigners, but not citizens, to obtain an exit visa before leaving the kingdom.
Conditions of issue
Some visas can be granted on arrival, usually only to citizens of countries enjoying good relations with the issuing country, or by prior application at the country's embassy or consulate, or sometimes a specialized travel agency with permission from the issuing country. If there is no embassy or consulate in one's home country, then one would have to travel to a third country and try to get a visa issued there. The need or absence of need of a visa generally depends on the citizenship of the applicant, the intended duration of the stay, and the activities that the applicant may wish to undertake in the country he visits; these may delineate different formal categories of visas, with different issue conditions.
Some countries will have reciprocal visa regimes. This means that if Country A requires citizens of Country B to have a visa to travel there, then Country B will apply reciprocity and require a visa from citizens of Country A even if Country B's citizens are not a migratory problem for Country A. Brazil, for example, imposes a visa requirement on United States, Australian and Canadian citizens because those three countries have imposed a visa requirement on Brazilian citizens.
A fee may be charged for issuing a visa; these are typically also reciprocal, so if country A charges country B's citizens 50 USD for a visa, country B will often also charge the same amount for country A's visitors. The fee charged may also be at the discretion of each embassy and can be increased to discourage unserious applicants. A similar reciprocity often applies to the duration of the visa (the period in which one is permitted to request entry of the country) and the amount of entries one can attempt with the visa. Expedited processing of the visa application will also generally incur additional charges.
The issuing authority, usually a branch of the country's foreign ministry or department (e.g. U.S. State Department), and typically consular officers, may request appropriate documentation from the applicant. This may include proof that the applicant is able to support himself in the host country (lodging, food), proof that the person hosting the applicant in his or her home really exists and has sufficient room for hosting the applicant, proof that the applicant has obtained health and evacuation insurance, etc. Some countries ask for proof of health status, especially for long-term visas; some countries deny such visas to sufferers of certain illnesses, such as AIDS. The exact conditions depend on the country and the category of visas. Developed countries frequently demand strong evidence of the intent to return to the home country, if the visa is for a temporary stay.
The issuing authority may also require applicants to attest that they have had no criminal convictions, or that they do not partake in certain businesses (like prostitution or drug trafficking). Some countries requested information as to the ideological leanings of the applicant; this used to be the case of the United States, which inquired whether visa applicants were Communist sympathizers (and denied visas to known or suspected sympathizers.)
Bearers of official, and especially diplomatic, passports are generally subject to supplemental checks (diplomatic personnel must be formally recognized as such by the host country to benefit from diplomatic immunity.)
Types of visa
Common types of visas are:
- transit visa, usually valid for 3 days or less, for passing through the country to a third destination.
- tourist visa, for a limited period of leisure travel, no business activities allowed. Some countries (e.g., Kuwait) do not issue tourist visas. Saudi Arabia introduced tourist visas only in 2004 although it did (and still does) issue pilgrimage visas for Hajj pilgrims.
- business visa, for engaging in commerce in the country. These visas generally preclude permanent employment, for which a work visa would be required.
- temporary worker visa, for approved employment in the host country. These are generally more difficult to obtain but valid for longer periods of time than a business visa. Examples of these are the United States' E-3, H-1B and L-1 visas.
- on-arrival visa, granted immediately prior to entering the country, eg. at an airport or border control post. This is distinct from not requiring a visa at all, as the visitor must still obtain the visa before they can even try to pass through immigration.
Less common visas include:
- student visa, which allows its holder to study at an institution of higher learning in the issuing country.
- working holiday visa, for individuals traveling between nations offering a working holiday programme, allowing young people to undertake temporary work while traveling.
- diplomatic visa, which confers diplomatic status on its holder and is normally only available to bearers of diplomatic passports.
- journalist visa, which some countries require of people in that occupation when travelling for their respective news organizations. Countries which insist on this include Cuba, Iran, North Korea, Saudi Arabia, the United States (I-visa) and Zimbabwe.
- fiancee visa, granted for a limited period prior to intended marriage based on a proven relationship with a citizen of the destination country: for example, a German woman who wishes to marry an American man would obtain a Fiancee Visa (also known as a K-1 visa) to allow her to enter the United States.
- immigrant visa, granted for those intending to immigrate to the issuing country. They usually are issued for a single journey as the holder will, depending on the country, later be issued a permanent resident identification card which will allow the traveller to enter to the issuing country an unlimited number of times. (for example, the United States Permanent Resident Card).
Entry and duration period
Visas can also be single-entry, which means the visa is cancelled as soon as the holder leaves the country, double-entry, or multiple-entry, permitting multiple entries into the country with the same visa. Countries may also issue re-entry permits that allow temporarily leaving the country without invalidating the visa. Even a business visa will normally not allow the holder to work in the host country without an additional work permit.
Once issued, a visa will typically have to be used within a certain period of time, and the period of validity starts only on entry into the country. A notable exception to this is India, where the visa validity period starts at the time the visa is issued.
The validity of a visa is not the same as the authorized period of stay in the issuing country. The visa validity usually indicates when the alien can apply for entry to the country. For example, if a visa has been issued January 1st and expires March 30th, and the typical authorized period of stay in a country is 90 days, then the 90-day authorized stay starts on the day the passenger reaches the country, which has to be between January 1st and March 30th. The traveller could therefore stay in the issuing country until July 1st.
Once in the country, the validity period of a visa or authorized stay can often be extended for a fee at the discretion of immigration authorities. Overstaying a period of authorized stay given by the immigration officers is considered illegal immigration even if the visa validity period isn't over (i.e. for multiple entry visas) and a form of being "out of status" and the offender may be fined, prosecuted, deported, or even blacklisted from entering the country again.
Entering a country without a valid visa or visa exemption may result in detention and removal (deportation or exclusion) from the country. Undertaking activities that are not authorized by the status of entry (for example, working while possessing a non-worker tourist status) can result in the individual being deemed removable, in common speech an illegal alien. Such violation is not a violation of a visa, however despite the common misuse of the phrase, but a violation of status hence the term "out of status."
Even having a visa does not guarantee entry to the host country. The border crossing authorities make the final determination to allow entry, and may even cancel a visa at the border if the alien cannot demonstrate to their satisfaction that they will abide by the status their visa grants them.
Visa and immigration laws may be very different among countries. As such, aliens are advised to check with immigration lawyers for visa and immigration laws governing the countries they wish to enter and eligibility to receive visas or other immigration benefits.
Visa refusal
A visa may be denied for various reasons, for example (but not limited to):
- if the applicant has committed fraud or misrepresentation in the requirements;
- if the applicant is felt to be intending to stay permanently while applying for a temporary visa;
- if the applicant does not have a genuine reason for their journey;
- if there is already an immigration problem in the country the applicant intends to visit;
- if the applicant is asking for a resident visa and has no visible means of sustenance;
- if the applicant has a criminal record;
- if the applicant does not have a good moral character;
- if the applicant is considered to be a security risk;
- if the applicant has not completed his military service to the state;
- if the applicant is a citizen of a country with whom the host country has poor or non-existent relations (for example, North Korea rarely grants visas to American citizens).
