I'm new to Slavic languages, and I consider Polish to be the most useful and influential one after Russian. What do I need to know before I start so I don't get too frustrated and have a better experience? I'm from Latin America and plan to leave my country after I finish college to pursue my career as an engineer. I was thinking of going to the United States, but things don't look good for us immigrants there. I want to be prepared when I leave my country.
