Letters of Invitation

You must have paid the registration fee to receive an invitation letter. If you require an invitation letter, please contact the ASLO 2019 conference registrar, Jo Davis, at We recommend that you do this as soon as you submit your abstract to ensure that you receive your visa and travel documents in time for the meeting. Your presentation assignment is not required for your letter of invitation to be issued.

Please note: We are unable to send invitation letters directly to consulates on behalf of a potential attendee. Invitation letters are prepared solely for individuals who have paid their registration fees to attend the meeting, and such documents will be emailed directly to the participants. It is your responsibility to ensure documentation is correct and completed in a timely manner before you start your journey. We recommend you apply for your visa at least 10 weeks before you travel (earlier in some cases). For more information, contact your nearest embassy or consulate.

Spouse and guest fees cover only the conference social events such as the Sunday welcome reception and other receptions, and coffee services. Optional events such as any special activities are not included. The guest/spouse fee does not include admission to the plenary or concurrent sessions.

All registrations must include complete credit card information, including number, CVC code, expiration date, and cardholder name. VISA, MasterCard, and American Express are accepted. Organizations can be billed only if a purchase order accompanies the registration either electronically or by mail.
