I realize that the question of the effects on the United States of a looser policy (sometimes even no restrictions) in regards to immigration in the 1800s has been asked before. But, what I want to ask is what the effects on the rest of the world be of the US gaining more immigrants than OTL and thus having a larger population.
There are two specific scenarios I want to ask about:
1) Simply put, the policies of the US (in the 1800s) in regards to immigration are looser (perhaps due to a different mindset towards immigrants from specific areas of Europe and Asia) or at the very least delayed in relation to OTL to allow for higher numbers of immigrants than OTL.
2) The colonization of North America by the Dutch and the Swedish are more successful, leading to the creation of more settlements and higher population than OTL. Assume that in this scenario, the Dutch and Swedish still lose their colonies to the British (say, the colonies were either sold for financial problems or they lose them in a war, like for example the Dutch-Anglo Wars which could still happen in this scenario), and years later, the US still becomes independent of the British (obviously with some differences).
The latter scenario may not be plausible, or at least, as fleshed out as it should be, but I just thought this up recently. It may also lead to the greatest amount of butterflies, which is why I bothered to include it. I didn't include a scenario in which there are no restrictions what so ever as that's quite unrealistic and borderline ASB.
