Meetings: Hotels and Travel
If you will require a visa to enter the United States to attend the 2011 AAAS Annual Meeting, 17-21 February 2011, in Washington, DC, begin planning for the application process now.
Even if you didn't need a visa for a previous Annual Meeting, you are encouraged to double-check the current requirements In addition, U.S. regulations now require security checks for most visitor visas, resulting in a process that may take more than three months. Citizens of certain countries must have an invitation in hand before they can obtain a passport from their government, and then apply for a U.S. entry visa. After registering for the meeting, a letter of invitation will be sent by e-mail to all international registrants.
Citizens of Visa Waiver Program countries (VWP) generally do not need a U.S. visa for business or tourism visits of less than 90 days unless they are receiving any compensation for services or activities such as lectures or presentations; however, as of January 12, 2009, all travelers coming to the United States from any of the 36 Visa Waiver Program countries are required to complete an on-line travel authorization form before their travel. This new program, called the Electronic System for Travel Authorization, or ESTA, is administered by the U.S. Department of Homeland Security. Travelers without the ESTA authorization will not be permitted to enter the United States.
Once again, even if you didn't need a visa before, we strongly advise you to check the current U.S. requirements. Official information on U.S. visa policies and procedures is available from the U.S. Department of State.
