# Remote participation fee waivers

We understand that not everyone can afford the remote registration fee and so we make an unlimited number of remote participation fee waivers available. This operates on a trust basis with no checks on eligibility, and the list of fee waiver recipients is kept confidential. If you wish to participate remotely but cannot afford the registration fee then please take the fee waiver option:

# Registration changes and cancellation

If you register for onsite participation and wish to change to an online registration then you can cancel with a full refund and re-register. If you wish to cancel your registration for any other reason please contact us. Further details about IETF meeting registration, including terms and conditions, are available at: 

    https://www.ietf.org/meeting/terms-and-conditions/

# Meeting venue and hotel reservations

The meeting venue is Hilton Vienna Park, which is also the main IETF hotel. Details can be found on the IETF 126 Meeting Venue and Hotel page:

    https://www.ietf.org/meeting/126/hotel

To ensure that our room block is only used by IETF participants, the link to register is only provided after registration and we ask you not to share it.

# Visas

For this meeting, the Letter of Invitation (LOI) is issued by local supporter next layer. For more information please visit:

    https://www.ietf.org/meeting/visas/

We are experiencing an increasing number of attempts to obtain our LOIs by people who are unrelated to the IETF. To ensure that we do not inadvertently support visa fraud we are applying a higher level of scrutiny to all of our support for visa applications. We apologise in advance for any friction this might cause.

# Agenda

A preliminary agenda will be published on 19 June 2026.
