SpaceX cannot hire non-US Citizens because of ITAR.

This is not exactly correct. They can also hire permanent residents (aka green card holders).

And it is possible to get waivers for particular individuals. However, because of the process involved, it is unlikely to be pursued by someone like SpaceX except in very exceptional cases of getting known international experts.

I have quite a few friends with a green card working for SpaceX. So, it's definitely not an issue for them.

[goodcanadian]

I wasn't talking about green cards. I was talking about "non-US" persons. In other words, I was adding additional information to your comment, not contradicting it in any manner.

[krasin]

Apologies, I misunderstood it. You're right.

Or at least, it is often prohibitively difficult to do so.

That Werner Von Braun dude got so lucky.

He had an ITAR waiver...
