No, that is incorrect. The United States is the only G7 country that doesn't have straightforward, non-lottery ways to obtain permanent legal residency and work status. In most developed countries the idea of a non-immigrant work visa is extremely limited; once you are in the country you are accumulating time toward obtaining permanent residency.

The US immigration system is a series of exceptions and loopholes, if you investigate the process for immigrating to any other G7 country you will find that there is a general "skilled migrant" category with some basic requirements (such as education, language proficiency, good health) that more or less guarantees eventual citizenship once obtained.

Australia's immigration policies appears to be lot more open than America's. As long as you have certifiable skills, and have stayed here the mandatory amount of time, you are almost guaranteed a permanent residency, after which point you are almost guaranteed a citizenship.
