Visitors to the USA must have a valid passport. A visa is required for citizens of countries that do not participate with the Visa Waiver Program with the United States. Conference participants should familiarize themselves with visa requirements well in advance of the conference. The LIP-2018 Conference organisers encourage you to apply for your visa as early as possible, at least 3 to 4 months prior to the conference. Learn more about the list of countries participating in the Visa Waiver program.

How to Obtain a Visa
Complete information on how to apply for a VISA to enter the US can be found on the U.S. Department of State’s website.

Attendees of a scientific conference should apply for a “Business (B-1)” Visa. Learn more about obtaining a Business Visa.

Interview Preparation

As part of the visa application process, an interview at the embassy consular section is required for visa applicants from age 14 through 79, with few exceptions. Persons age 13 and younger, and age 80 and older, generally do not require an interview, unless requested by embassy or consulate.

• Applicants should be able to answer specific and detailed questions related to their purpose of travel, business dealings with the inviter, and their general business relations (as appropriate, depending on their job responsibilities).
• Applicants should be able to provide complete travel itineraries and (if appropriate) conference schedules.
• Applicants who claim to have existing relationships with their inviters or other U.S. entities, should provide clear proof of these relationships. For instance, through purchase orders, correspondence, letters of invitation, etc.
• Applicants should be able to explain how the applicant’s visit will be funded.

NOTE: Proof of purchase of an airline ticket is not an item requested by the embassy to document your itinerary for your trip. No assurances regarding the issuance of visas can be given in advance. Therefore, final travel plans or the purchase of non-refundable ticket should not be made until a visa has been issued and you are in receipt of the passport.
