I'm based in Europe and my university is outside the visa waiver program for some of my co-authors. How early should they apply for a visa to attend a US conference in spring?
Visa timeline for attending a conference in the US?

Start as soon as you have the acceptance letter. Interview wait times vary a lot by consulate, sometimes several months.
Ask the conference for an official invitation letter — most large conferences have a form for this on their registration page.
Also check whether the conference offers a virtual presentation option as a backup, in case the visa doesn't come through in time.
