Travelers need to express the purpose of their visit to the Immigration Officer at their port of entry to obtain either WB (Waiver for Business) or WT (Waiver for Tourist) status on their I-94 Arrival/Departure Card. Any error should be corrected prior to leaving the U.S. Customs and Border Protection (CBP) inspection area. Visitors are urged to speak with a CBP supervisor if necessary. Status and length of stay as a visitor to the U.S. are defined by what is written on the I-94 Arrival/Departure Card by the U.S. CBP immigration officer upon entry. Extensions of stay or changes to another visa status are NOT available.
If your country does not participate in the VWP, you must obtain a B-1 (business) or B-2 (tourist) visa before entering the US. Information on the B-1 and B-2 visas can be found at US Embassies or Consulates. Please note that obtaining a B-1 or B-2 visa can be a lengthy process, so begin the process of obtaining a visa soon. For invitation letter for the visa application, please contact to the workshop local organizers.
