That's all employees, not just engineers.

Do you think twitter has a lot of marketers, PR, product managers under H1B? I don't have data, but in the tech companies I have worked at it engineers were the H1B visa holders, almost exclusively.

They absolutely have a number of PMs on work visas. I'm friends with a lot of them.

I would imagine the vast majority of those are engineers. It’s pretty hard to get an H1B in a non technical field and I’m not sure Twitter would even have many of those types of jobs.

H1-B is for "highly skilled" workers, what skilled workers would Twitter have other than developers?

"fashion models of distinguished merit and ability"

Potential trophy wives of billionaires, of course.

Is the assertion here that Twitter is employing H1-B fashion models?

You can look at the NAICS codes, the overwhelming majority are 54.

So maybe 20-30% of dev, which would be overrepresented here?

I think that may be outdated. Searching at https://www.uscis.gov/tools/reports-and-studies/h-1b-employe... yields around 60 applications in 2023 (but note that I'm not sure how things are counted given that H-1B is valid for 3 years).

The year is also only half over.

IIRC the H-1B application period is some time in the first half of April every year (so all the ones that would be filed this year have already been filed), but IDK if renewals need to catch that train.

Edit: clarifications.

H-1B approval has two stages, the registration period (March/April) and the petition period (ends 90 days after post-registration selection). AIUI this is counting petitions (i.e. I-129s), so won't be accurate until at least 90 days after selection notices - which would be around now - but then the site itself says it can further trail by a quarter.
