We encourage you to first contact the consulate to determine the wait time for an interview. If you require a letter of invitation before submitting an abstract or you will not be submitting an abstract, you must request one via email. After submitting an abstract, you can automatically generate a letter of invitation through the abstract submission system.

Effective 20 January 2011, citizens of the Visa Waiver Program (VWP) countries will be unable to enter the United States without Electronic System for Travel Authorization (ESTA) approval from the U.S. Government.

Visa Appointments

AGU has registered AGU23 with the U.S. Department of State to assist with visa appointments. All scientists with accepted abstracts should have received an invitation letter as part of their documentation to help with the visa process. If you did not submit an abstract and need assistance obtaining an invitation letter, please contact the Member Services Team.

After applying for a visa appointment, the next potential step to help with your visa process is to contact the National Academies of Science, Engineering and Medicine International Visitor Office (IVO). They often assist scientists with expediting the visa process to get appointments moved.

Scientists who have been accepted as speakers or attendees for AGU23 may request help from IVO to expedite the visa process by completing the Visa Questionnaire on their site. This questionnaire should be completed after you have already reserved a visa appointment in your country. An already established visa-appointment is crucial to working with the IVO, even if that appointment is in 2024.

Because of the personal information the IVO needs to move forward with requests, AGU staff or volunteer leadership are unable to make a visa request on behalf of a scientist. The IVO has provided a checklist to help you prepare for their Visa Questionnaire needs.

Health & Safety

Safety & Security

AGU is working with local city officials and law enforcement, along with a risk assessment firm and a private security company to provide a safe and comfortable environment for all AGU23 attendees. The city of San Francisco also has a Welcome Ambassador Program in place to create a welcoming, positive, and secure experience downtown. The program features ambassadors wearing distinctive orange jackets positioned around the city and ready to escort attendees to and from various related AGU23 locations including the Moscone Center, hotels and restaurants.

Health & COVID-19

American Geophysical Union (AGU) is committed to providing a safe and healthy environment for all Fall Meeting participants and staff. We continue to monitor health and safety issues such as the COVID-19 pandemic and follow CDC guidelines as they are released. 

AGU strongly encourages all attendees to be up-to-date on all vaccinations. AGU will not require the validation of vaccine information via a third party. However, we will reconsider this requirement if conditions and guidance from health professionals change. 

Masking requirements will be assessed near the meeting dates and will be available onsite for any attendee who needs them. 

Safe AGU

AGU is committed to promoting a safe work environment in the Earth and space sciences and ensuring that all AGU program activities are free from discrimination, bias or harassment of any type. One way we do that is through our Safe AGU program at AGU meetings, which includes workshops for attendees. This program was designed to promote safety and offer support to meeting attendees who may feel harassed, threatened or unsafe in any way when participating in AGU Meetings.

Volunteers and staff at AGU events wearing Safe AGU buttons have been trained to assist those who experience unsafe or inappropriate behavior. If you are unable to find someone with a SafeAGU button during AGU23, please visit the Meeting Services desk at Moscone West Registration.
