Because the rules and process (hence the processing
time) for applying for entry into the United States can change suddenly,
travelers are advised to monitor the situation closely. We recommend
• US National
Academy Int’l Visitor’s Office
• US State Department,
Visas may be necessary for entry into the United States to attend the CLIVAR
Conference. Citizens of certain countries may benefit from the Visa
(VWP) if they meet the necessary qualifications (see below). Non-qualifying
foreign citizens must apply for a visa at an American embassy or consulate abroad,
desiring to travel to the United States.
Visa Waiver Program (VWP)
Currently, 27 countries participate in
the Visa Waiver Program:
Andorra, Australia, Austria, Belgium, Brunei,
Denmark, Finland, France, Germany, Iceland, Ireland, Japan, Liechtenstein,
Luxembourg, Monaco, Netherlands, New Zealand, Norway, Portugal, Italy,
San Marino, Singapore, Slovenia, Spain, Sweden, Switzerland, United
To enter the US on the VWP, travelers from
participating countries must:
• Be seeking entry for 90 days or less,
as a temporary visitor.
• Be a citizen (not merely a resident) of the Visa Waiver country.
• Have a valid passport issued by the participating country. Additionally,
starting October 1, 2003, the passport presented at the US port of entry must
be a machine-readable passport.
• If entering by air or sea, have a round-trip transportation ticket issued
on a carrier that has signed an agreement with the US government to participate
in the VWP, and arrive in the United States aboard such a carrier.
• Hold a completed and signed Nonimmigrant Visa Waiver Arrival-Departure
• Form I-94W, on which he/she has waived the right of review or appeal
of an immigration officer’s determination about admissibility, or deportation.
These forms are available from participating carriers, from travel agents, and
at land-border ports-of-entry. (Travelers should consult carriers to verify which
ones are participating before making travel arrangements.)
• Entry at a land border crossing point from Canada or Mexico is permitted
under the VWP. Travelers who apply for entry at a land border crossing point
are not required to present round-trip transportation tickets or arrive at the
border entry point aboard a carrier who has signed an agreement with the US to
participate in the VWP. All other VWP requirements apply to such travelers.
You can use the VWP for business and tourism. You can do things on the VWP
that you can do on the B-1/B-2 non-immigrant visa. If you don’t know
whether your planned activities are permitted on the VWP, please contact the
consular section of the embassy or consulate that serves your area for information.
As soon as you contemplate travel to the US, and after identifying that a visa
is needed, contact the US embassy or consulate for information about current
visa processing time estimates and processes. It is important to apply very
early. As of this date, visa applications should be sought at least three months
in advance of anticipated travel.
All visitor visa applicants must have the following:
• Nonimmigrant Visa Application, Form DS-156, completed and signed
• Current, valid passport or travel document
• Photograph (2 x 2 inches, passport type)
• Application fees. All applicants must pay the application fee. Some applicants,
according to nationality and type of visa, must also pay an issuance fee
• Evidence of funds to cover expenses in the United States
• Evidence of compelling social and economic ties abroad
• There may be other forms and documentation. Please check the indicated
web site or contact a local US embassy or consulate for further information.
