In ideal world yes, but reality is that it requires significantly more effort, e.g.: "anywhere in the world" would really mean "anywhere in the world except Iran, Crimea, and other countries/regions that US thinks you should not do business with". Sometimes a company may not be even allowed to have non-US citizen employees.

Then, you have to make sure you can handle payroll, taxes, and overall operations.

It doesn't have to be all or nothing: expanding from an office-centric to all-US is a good start - baby steps.
