If someone wants to come to this country and build a life here, I welcome them. My ancestors did it a few centuries ago (pre-Revolution). My wife's ancestors did it about a century ago. I don't want to "close the door", simply because I'm already here.
But, I expect them to apply for citizenship as soon as they are eligible, or return to their country or origin. You want to live in American, you become an American.
And until you are a citizen, you are on your own. No welfare, no Social Security, no government freebies or benefits of any kind. If you need help, there are many mutual aid societies organized by religion, culture, or nationality.
Until then, you are a guest, and are expected to act like one. If you wear out your welcome, it's time for you to go back to your home.
No limits? Is that the sole criterion to allow people to enter this country? Immigration to America is a privilege, not a right. And our immimgration policy should promote US national interests. There are literally billions of people who want to come here. We take in 1.1 million legal permanent immigrants a year, more than the rest of the world combined. We need to drastically reduce legal immigration. In 1970 we had 9.7 million foreign-born; today it is approximately 45 million.
No one is saying we should close the door, but our immigration numbers need to correlate to our needs. We decide who comes in, not the intending immigrant. We shouldn't be importing poverty and hundreds of thousands of high school dropouts annually.

No Social Security? Do you expect them to pay into the system and not receive benefits? Or if you make them exempt from paying in social security, you make them more attractive to employers than the native born. Their American-born children are automatically citizens thru birthright citizenship. They are entitled immediately to all the benefits any other American citizen is.
