    Visa Letter

    Notice on Visas

    If you plan to attend an AIAA conference or course held in the United States and you require a visa for travel, it is incumbent upon you to apply for a visa with the U.S. Embassy (consular division) or consulate with ample time for processing. To avoid bureaucratic problems, AIAA strongly suggests that you submit your formal application to U.S. authorities a minimum of 120 days in advance of the date of anticipated travel. 

    To request a letter of invitation, please fill out and submit the online Invitation Letter Request Form. You can also request a letter of invitation by contacting:

    ATTN: Customer Service
    American Institute of Aeronautics and Astronautics
    1801 Alexander Bell Drive
    Suite 500
    Reston, VA 20191-4344
    Phone: 703.264.7500
    Fax: 703.264.7657

    AIAA cannot directly intervene with the U.S. Department of State, consular offices, or embassies on behalf of individuals applying for visas.
