"which country you are a citizen of makes a HUGE difference" While it makes a big difference in getting into the US (legally) and acquiring whatever visa you need, it makes no difference whatsoever with regards to requirements to work legally within US. You have to have legal authorization to work in the US (i.e. either being a citizen, permanent resident or a temporary resident) regardless of your citizenship.
