I did NOT want to stay here. In 1960 era student visa holders were allowed to work max 18 months after graduation if work was in related field as study. Since I spent my own money at the university (actually my parents money, I was only 20 years old in 1960) I accepted a job offer from Link-Belt company in Chicago, to recuperate my college expenses in United States. When my 18 months work about to expire, I gave 2 weeks notice to quit. My employer wanted me to keep working. Their lawyers worked with immigration to change my student visa to permanent resident visa. I could not have done it without company sponsorship. Then I met an American woman, we got married and I decided to stay. Marriage would also have made me eligible for immigrant visa.
Actual immigrant visas are the way to do it. Marrying a US citizen also assures immigrants are required to not get on welfare for ten years and that someone is there who can help socialize the newcomer, along with the responsibility of that person for those ten years.
H1-Bs don't get that. They bring in their families and spouses and their former country's set of expectations and don't assimilate well, because they don't have to. Chain migration is a big thing with H1-Bs all around me, but I've been to a wonderful wedding anniversary and birthday parties, as well. This is transplanting a country.
This is also true of people “rescued” from places like Somalia, and they, too, don't assimilate, but bring their culture. We see what that is doing, right now.
We need to cut off these paths. Every country in the world exists for only its own citizens. No country exists for another country's citizens—period. If we collapse that, we deserve all the illegals and unlimited “legals,” we get, and will disappear as a country (and are).
