For people outside the US: would you travel to the US now? What if your employer asked you to do it - what would you say? How do you feel about conferences and events held in the US?
I would say I wouldn't go.
Holding conferences on the US was already a complete barrier, as it would require a work visa, and even if I really wanted to go, I'd need every information and inscription to be available 6 months in advance.
Yes. I would go to a conference to the USA, although that's incredibly rare that Canadian companies pay for the travel. Local conferences ( same city as the office one employed ) are OK though.
