You understand wrong. I am an immigrant myself and literally experienced what I said. I merely recounted my own experience and the hoops I had to go through to be admitted into the country and be allowed to stay permanently. I have first hand experience of what the USCIS requires and checks in order to be granted work visas and the entire lengthy and expensive process to get permanent residency if you’re coming from a third world country. You are literally asked in application forms if you’ve ever applied for government benefits and how much debt you currently have, because that raises flags for them. You also have to prove your skills by showing evidence of the work you’ve done and what special skills or knowledge you have that a local can’t otherwise do. I’ve been denied a visa once just because the consular officer wasn’t convinced that my skills were special enough. It was a long drawn out process just to get admitted in. Oh and you also need to undergo a medical exam because they want to make sure you don’t have any serious issues that can potentially make you a burden to the healthcare system.

So before accusing someone of arrogance and bigotry, make sure you actually know where the person is coming from. I am not against immigration at all. I am merely explaining how the government picks and chooses who to admit into the country through their standard immigration processes. Show me a first world country that doesn't have those requirements (except for asylum seekers). I'll wait.
