Please be aware that visa issuance cannot be guaranteed. Visa decisions are made solely by the US Department of State.
* The US Department of State has the authority to request special security clearances before issuing a visa. These clearances can take from 1 week to 2 months. Do not be alarmed if you are told that a security check will be done. In most cases, they are completed within a week or two.
* It is not possible for the conference organizers to expedite visas for conference participants.
Therefore, if a visa is required, you must plan ahead and apply for your visa as early as the US Consulate allows (but no more than six months in advance of your travel date). Each Consulate has rules about how early you may apply. Please follow the instructions of the Consulate where you plan to apply for the visa.

When you arrive at the US immigration inspection point (airport or border crossing), you must show your conference invitation letter and/or conference registration materials and a valid passport. We suggest that you also present your ESTA authorization page. Be sure to have these documents available to present to the immigration inspector. Do not pack them in a suitcase. When asked your purpose for entering the US, you should respond “to attend a professional conference.”
