You know what else is "their culture?" Cheating.
This comes from a friend and former coworker of my brother during college who was ashamed of being Indian. No lie, it's the streetshitter culture to do literally anything to get good grades, and that means rampant cheating literally everywhere. All the way through high school, pajeets will cheat their way to the top, and everyone turns a blind eye because the test scores are so good. Then they use those amazing but fake grades to get scholarships in the US, who are often more than happy to get international students to make themselves look more global and cosmopolitan, bumping out potential domestic students in the process. Then they continue their cheating streak because they know they'll get away with it. And then they'll get hired on H1-B visas because they're fine with being paid literal slave wages, depressing wages for Americans and fucking them out of their jobs. And that's why the tech industry is so shit these days.
The biggest thing I hated while I was in university was the fact that I couldn't get a summer job being a teaching assistant. All those positions were reserved for the international (read: pajeet) students so that they didn't have to go back to their home countries (read: Pooland) for the summer. So I was fucked out of a job even in college.
Oh, and almost all of the grad student offices smelled like curry. Fucking disgusting.
The best advice I can offer is what some of the other anons have: you're probably going to have to find a job at a smaller company, one that won't have the resources to go through the trouble of getting H-1Bs. Either that, or you might have luck finding remote work. Or alternatively, do something that's not tech-related, even if it's a waste of your degree. Getting my degree made me hate computers.
