All nationals listed in the chart above are eligible to apply online for an e-Tourist Visa (eTV). You must apply at least four days before you arrive in India. You can only enter India via those airports listed on the eTV website. There are five e-Visa subcategories: e-Tourist visa, e-Business visa, e-Medical visa, e-Medical Attendant Visa and e-Conference Visa.
A visa does not guarantee entry into the United States, but allows a foreign citizen coming from abroad to travel to a U.S. port of entry and request permission to enter the United States. The Department of Homeland Security, U.S. Customs and Border Protection (CBP) officials have authority to permit or deny admission to the United States, and determine how long a traveler may stay. At the port of entry, upon granting entry to the United States, the Customs and Border Protection officer will stamp your travel document with the date of admission, the class of admission (i.e. VWP traveler, or the visa classification for visa holders, or other permissible class of entry), and the date that you are allowed to remain until, that is the date by which you must leave the United States. You can review information about admission on the CBP website. The Department of State's Consular Affairs website has more information about duration of stay.
This document may be denied for any number of reasons. People with certain infectious diseases, for example, may be told to seek treatment for those diseases before a visa will be issued. They may also be denied to people who could potentially strain the system of the country they are visiting: for example, someone without enough money to get by might be denied a visa out of concern that he or she could rely on public assistance for help.
Visa and MasterCard are international settlement & clearing houses that help transfer of funds from one entity to the other. For ex: You might have a credit card from XYZ Bank. If you need to use your credit card at a merchant shop, that shop would need to have a machine provided by XYZ bank installed. Only then the shop keeper can accept your payment using the XYZ card.
Goods that you declare will be inspected by a biosecurity officer, who will assess the level of risk associated with the goods. In most cases, goods are low risk and will be returned to you after the inspection. However, if a biosecurity officer deems the goods to have some risk you can pay for the goods to be treated, pay to export the goods, or voluntarily dispose of the goods.
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.
A U.S. nonimmigrant visa grants you permission to travel to a Port of Entry (airport/seaport) in the United States. When you arrive at your destination Port of Entry, the U.S. Customs and Border Protection officer who processes your entry will determine the length of time that you may remain in the country. You may travel to the Port of Entry during the validity of your nonimmigrant visa up to and including the last day the visa is valid. The visa duration does not determine the length of time that you may legally remain in the United States; only the Customs and Border Protection officer can decide this upon your arrival in the United States.
The Democratic People's Republic of Korea (North Korea) requires that its citizens obtain an exit visa stating the traveller's destination country and time to be spent abroad before leaving the country. Additionally, North Korean authorities also require North Korean citizens obtain a re-entry visa from a North Korean embassy or North Korean mission abroad before being allowed back into North Korea.
