It's 3-4 years these days, unless you qualify for EB-1. Every step in the process takes a few months longer than it used to. But those numbers are not comparable. In most European countries, you first spend a number of years on a temporary residence permit, and then you can apply for permanent residence. That application typically takes less than a year to process. In the US, you can apply for permanent residence any time, but the application process takes several years.
