Unless you have family sponsoring you or $500k or $1m to invest, then there is no reliable path to permanent residence/green card. You are at the mercy of an opaque organization that answers to no one and also at the mercy of having an employer willing to take you on and jump through many hoops.
I could go on at length at what is fucked up about the US, and I could go on at least as long about what’s great about it. Some things are better here, some are...pitiful. My wife never adjusted to the lower standard of living in the US (the 1% don’t live as well as the 50% in Europe for example) while I found it more than compensated by the work and other interesting things.
