alt Hacker NewsI know the US gets a lot of flak due to the current administration's policies and actions. Despite that it is still the best country for immigrants with the caveat 'Assuming the immigrant makes every effort to integrate (learning the language, respecting local people/customs etc)'
More generally, I'd say the Americas are a step above Europe when it comes to ease of integration. In South America, people often assumed I'm immigrating, and made it clear I was welcome. In Europe, where I actually tried to immigrate, I'm treated as just a long-staying tourist. (Not blaming anyone here, they can run their countries however I want, but it's just silly to expect that people who have choice would come to Europe.)
