B1/B2 US visa when working remotely for a US company from Canada and also a student
score:3
Accepted answer
In case it helps someone in the future, here's what I did:
When asked for the purpose of my trip, I provided both reasons.
Since they already knew I was a student from previous applications, they simply confirmed whether I was still a student (which I am), and asked for a brief summary of the topic of the conference. My employment never came up.
I was not asked about my graduation timeline.
They seemed to approve the visa (at least, they held on to my passport).
