Which is not an issue for people immigrating from Europe.

In what way? Unless I've missed something significant the visa options for those emigrating from Europe to the US are limited. What options are there other than the H1B?

Not 'significant' but you can use L1 internal transfer visas after you work for a while in a branch of an American company.

American company also means a sales or support office (if registered correctly) of a European company.

Some paths are quota based by country of origin, so getting a green card is exponentially harder for a Chinese or Indian citizen than an Aussie, for instance.

> Some paths are quota based by country of origin

Yes, but that has little effect on H1B visas. European applicants are in the same pool as everyone else.

> getting a green card is exponentially harder

Nobody mentioned getting a greencard, which is a problem in itself. Just a work visa. Which, if you're a European citizen, is dependent on a lottery.

Yeah, it's easier for an AU citizen to get a visa (because there's a special program for them), but you haven't said why it's easier for an EU citizen to get one. Please back up your claim.

Why is it not an issue? They have to compete for the same ~65K visas/year as everyone else.

No the quotas aren't evenly split.

It's a big issue and a primary reason why you don't see massive developer migration from Europe into US. Most devs in Europe are just comfortable enough to not want to deal with the whole H1-B hassle. People who are money-focused move to the few places in Europe that tend to pay more and/or switch to contracting, which is a hassle too, but still orders of magnitude smaller than trying to get into US.
