In the US there are states which would benefit from high immigration as opposed to the more popular coastal states.
I wonder if there is some way to use this as a way to ease some immigration laws.

But, NYC breaks down if another 8 million people move into it. San Francisco is 1/10th the size of NYC and it already can't handle the people it has.
The only way fully open and accepted and world-wide immigration works is under unconscionable "living area restriction" schemes limiting already overly-popular areas. You either pick an "open" area (Idaho! North Dakota!) or slot new people into some pre-allocated catchment areas/states with restricted residency/transit for the first 5-15 years of their relocation? But, that sounds a bit too ghettoy.
China can build new cities in the blink of an eye, even if some of them end up going completely unused. The US can't maintain the cities it has and spends $30 billion to dig a new 2 mile subway ($5 billion towards cost, $25 billion towards corruption). There are solutions to "everybody wants to live in a better place" problems, but it takes organization, time, resources, a vision for a better future, and generosity. The world isn't currently offering those as a packaged deal. Be 70s forward-thinking-by-30-years-ahead California, not 2010s only-plan-for-6-months-later California.
But, that's assuming "aspirational" immigration where 30 million to 300 million people would want to move "to the west" for a chance at a better life. What about "i got mine, i just want to move" immigration? NYC<->London? Sydney<->Chicago? Something between an educated worker visa and an investor visa? We don't have an answer for that. You are just incidental to a combination of where you were born and where your parents had citizenship at the time you started breathing outside the womb.
