> Diversity visa is your example, really? Diversity visa is completely random, that's what it's called the lottery.
All the quota-limited immigration visa categories are distributed, among those qualified, by lottery. Diversity visa aren't called "the lottery", the process for assigning all quota-limited visas is called that. The diversity visa is expressly skill-qualified, permanent, and independent of employer sponsorship.
> Employment based immigration requires an employer sponsor to file a petition.
True. For most employment-based categories, though there are several exceptions.
> Does not refute my point that there is no independent skilled permanent immigration scheme.
"independent" was never stated previously. The original claims were that there was no skill-based permanent immigration system and that it was all family-based. Permanent immigration to the US is not all family-based, as there are family-based, employment-based (most categories of which are skill-qualified), and diversity (which is skill-qualified) immigrant (permanent) visas.
