Yes
The US Federal Government has "sovereign immunity", so it cannot be sued without its consent.
Yes. It however, depends on what are you being sued for. For example, being sued for overdue alimony is perfectly doable within the laws of both countries.
The US Sued did win.
Every Canadian can have a job in the US government. The American are tolerable in that case. You only need the specif requirements that are needed for being a employee at the US government.
Read the Federal Tort Claims Act. It can be viewed online and defines the circumstances under which the government can be sued.
No. A business is fundamentally a "for profit" entity. The US Govt can engage in transactions with businesses, and can even allow itself to be sued as a result of those transactions. However, the US Government is wholly different sort of entity.
If an infringement case is brought, the financial situation of the infringer is immaterial: they can be sued for up to $30,000 per use in the US.
The 100 US senators serve only the US government
The US has only one president and he is the chief executive over the US government.
It depends. The 11th amendment grants states sovereign immunity from lawsuits. The state can waive its right to be sued by its own citizens, but it doesn't have to. The only way a state can be sued is if it is sued by another state. If two states sue each other, then the US Supreme Court has original jurisdiction. Downside is, you cannot sue your own state. BUT, municipalities and local governments do not have sovereign immunity, so you can sue your city government.
