Genuinely curious: why do we need H1B visas for artists? My understanding is that H1B visas are meant to cover highly-skilled work that can't be done by locals, and "art" doesn't seem like a field with a shortage of local candidates?
A famous supermodel can most likely get an O1 visa, for people of extraordinary ability. But agency models more commonly work on H1-B. Melania Trump is a famous example. These visas are tied to an employer and there's less portability. It's a two tier system.
Personally I think that there is some harm here. Agencies bring in young women from relatively poor countries and they are put in conditions where abuse, even sexual assault, is common and can face pressures to tolerate conditions and shoots that a local person with a safety network would not.
If these other professions don’t pay as much as swe, then doesn’t that indicate that domestic supply is meeting those industries needs better than it is swe?
If their art's got enough value to be valuable in the real sense, they're well above all this. Otherwise they're nothing.
