The sponsor usually can get them a green card.
Green card? We admit ONE MILLION legal immigrants with green cards EVERY YEAR. Most are not IT workers. Actually, most are low skills, low wealth people sponsored by a relative on green card himself/herself.
I am less worried about 50,000 H1-B visa temporary workers who actually have jobs and pay taxes, than the ONE MILLION legal immigrants admitted every year, without any test of skills or wealth. I personally know dozens and dozens of such green card holders who arrived as seniors, and are receiving social security checks without having paid a dime in taxes.
