Travel & Visa Information

We look forward to welcoming attendees to Neuroscience 2025 November 15–19 in San Diego. 

Non-U.S. residents may need a visa to enter the United States for Neuroscience 2025. If you already have a U.S. visa, check the expiration date to ensure your visa will not expire before or during your planned travel dates. Citizens of countries meeting the visa waiver criteria do not need a visa to enter the United States. If you are eligible to travel on the Visa Waiver Program, but prefer to have a visa in your passport, you may still apply for a Business (B-1) visa. A list of countries participating in the Visa Waiver Program (VWP) can be found on the State Department website.

Obtaining a Visa

After identifying that a visa is needed, foreign travelers should contact the U.S. Embassy Consular Section in their country to determine visa processing time frames. For up-to-date information, access the DOS website.

After completing the form, applicants will be able to download as a PDF an official letter inviting them to attend Neuroscience 2025.

Abstract presenters can download a letter of invitation that includes their abstract title by entering their abstract's control/tracking number. This number is found at the top of the screen in your Review My Work summary page in your abstract submission or on the receipt as the Control/Invoice number. Please only enter the 4- or 5-digit text in the middle of the number, for example: 12345, not 2025-S-12345-SfN. For questions about your control number, please email program@sfn.org.
