The main reasons states impose visa restrictions on foreign nationals are to curb illegal immigration, security concerns, and reciprocity for visa restrictions imposed on their own nationals. Typically, nations impose visa restrictions on citizens of poorer countries, along with politically unstable and undemocratic ones, as it is considered more likely that people from these countries will seek to illegally immigrate. Visa restrictions may also be imposed when nationals of another country are perceived as likelier to be terrorists or criminals, or by autocratic regimes that perceive foreign influence to be a threat to their rule.[77][78] According to Professor Eric Neumayer of the London School of Economics:
A business visa allows the bearer to enter the host country and engage in business activities without joining that country’s labour market. For example, an individual may require a business visa if they are travelling to a country to do business with another company or if they are attending a business conference. The visitor typically must show that they are not receiving income from the country.

H2-B Seasonal Worker Visas are nonimmigrant visas offered for temporary, irregular, or seasonal work. Jobs that are needed on a "one-time" basis or to help a company during moments of heavy activity also qualify. To get an H-2B visa, the position cannot be in agriculture or farming. Working at a hotel during the busy summer season or helping in the construction of a single building project are both examples of jobs that will likely meet H-2B requirements. To be eligible for an H-2B visa you must also be a national of a qualifying country. Learn more about H2-B visas.
The visa interview will take place at the U.S. embassy or consulate in the country where you live. You will be interviewed by a consular officer who will determine if you are qualified to receive a visa. He or she will review your documentation and visa application, ask you questions about your personal history and the reason for your trip to the U.S.
The Visa Waiver Program allows nationals of nations that are part of the Western Hemisphere Travel Initiative to enter the U.S. port of entry without a visa. The Visa Waiver Program paperwork is handed out on the transport to be completed by each eligible person; if security checks at the U.S. port of entry do not flag the traveler for any reason, entry is typically granted for a period not to exceed 90 days. Entry is granted on several strict conditions, the two most important of which are that the traveler has in their possession a return trip ticket to their country of origin or another country outside U.S. territory, and that the traveler will not seek or perform work, either paid or unpaid.
Iraq, Kuwait, Lebanon, Oman, Saudi Arabia and the United Arab Emirates all have an exit visa requirement for alien foreign workers. This is part of their kafala work visa sponsorship system. Consequently, at the end of a foreign worker's employment period, the worker must secure clearance from their employer stating that the worker has satisfactorily fulfilled the terms of their employment contract or that the worker's services are no longer needed. The exit visa can also be withheld if there are pending court charges that need to be settled or penalties that have to be meted out. In September 2018, Qatar lifted the exit visa requirement for most workers.[102]
Imagine your own ties in the country where you live. Would a consular office of another country consider that you have a residence there that you do not intend to abandon? It is likely that the answer would be "yes" if you have a job, a family, if you own or rent a house or apartment, or if you have other commitments that would require you to return to your country at the conclusion of a visit abroad. Each person's situation is different.
In accordance with the agreement signed between the United States and China to extend visa validity, beginning on November 29, 2016, Chinese citizens with 10-year B1, B2 or B1/B2 visas in Peoples’ Republic of China passports will be required to update their biographical and other information from their visa application via a website every two years, or upon getting a new passport or B1, B2, or B1/B2 visa, whichever occurs first.  This mechanism is called EVUS - Electronic Visa Update System.
Some countries, such as Canada and the United States, may require the visitor to include a letter of invitation with their travel visa application. A letter of invitation is a formal letter from the person you intend to visit stating that they are inviting you to visit them in that country. Invitation letters help travel authorities vet potential visitors by making sure that a temporary visit is indeed the true nature of the visa request. Check with your intended destination’s government website for details on what needs to be included in a such a letter.

An incoming passenger can import up to two pets at one time.

Citizens of member states of the Association of Southeast Asian Nations do not require tourist visas to visit another member state, with the exception of Myanmar. Until 2009, Burmese citizens were required to have visas to enter all other ASEAN countries. Following the implementation of visa exemption agreements with the other ASEAN countries, in 2016 Burmese citizens are only required to have visas to enter Malaysia and Singapore. Myanmar and Singapore had agreed on a visa exemption scheme set to be implemented on 1 December 2016.[88] ASEAN citizens are entitled to use the Burmese visa on arrival facility.
