Wow, my question may be stupid but since Riot events are considered international and happens often, requiring constant traveling. Can't their employees have acces to buisness section (or i don't know what's called, the one that gets you fast visas) ?
Most Riot employees including myself are probably free to live and work in the united states for a period of 90 days due to the ESTA program without a formal visa, but if you want to stay beyond 90 days and work, one needs an actual visa and that's what we're talking about here. You would almost certainly be able to attend/run an event in that 90 day period, so most of the time, you don't need a visa.
There are certain contingencies for large international businesses. For example, if one wanted to transfer an employee from Acme inc, Dublin to Acme inc, San Francisco, and one could demonstrate that employee had specialised knowledge that would be very difficult to hire for, one could file for an L-1b visa. If Acme inc was a very large business, it might have what's called an "L-1 blanket", which is where the US government recognises that the business needs to have it easier to move employees between countries.
However, L-1 blanket or not, unless you have an urgent need and/or are a healthcare professional, during COVID you will need to wait in the queue subject to consulate availability, just like everyone else. It's not the visa itself that takes time, it's getting in front of a consular officer to hear your case.
