Description
Non-U.S. citizens must complete an additional Brookhaven Lab Guest Form and be approved in the Guest Information System (GIS) if they would like to attend this meeting. This applies to both in-person and remote attendees!
If you have a current Brookhaven Lab guest appointment and a valid BNL Guest Number or you have a pending Guest Registration (GR) Number, it is not necessary to complete the additional Brookhaven Lab Guest Form again.
Registration Deadlines:
- US citizens: June 8, 2025
- non-US citizens: June 8, 2025
