It appears to be the case that visa applications were being handled fairly quickly from China for a couple of years, and people got used to it, so got in the habit of applying later. And then there was an unexpected increase in processing in time that coincided with this IETF. IOW the timing of visa applications isn't predictable by the IETF. If we make it possible to apply earlier and people don't apply earlier because they have expectations as to the speed of the approval process that wind up not being met, we can't do anything about that. And this can happen with any country: visa approval speed can vary depending on politics, staffing, a flu outbreak at the wrong time, a problem with the information systems at the embassy, etc. Also, when I've talked to my colleagues from other continents about this, I hear from a lot of them that despite the visa difficulties, coming to the U.S. is actually an attractive thing, because they can do business here that they couldn't do elsewhere. So while it would definitely be easier if we just had a barge outside the 250-mile limit with an airstrip, I don't think "choosing a location where getting visas is easy" is actually a practicable suggestion.
