Also, how would people in my home country perceive me?
Also curious as to how long I can stay legally, and if the US government would try to cause problems for me.
Bonus points if you can answer what would Native Americans would go though.
It's 1800. I want to emigrate to the US (from a country of your expertise).
umm... If my expertise was related to Australia, for instance, I would likely not know the process for immigrating to the USA. Only someone whose expertise was related to the USA itself would be able to answer this question.
This is purely a USA history question, not a "country of your expertise" question.
