Hiring someone across a national border adds a lot of complexity and cost to the employment process. A few companies I have worked for which did have foreign employees ended up with an umbrella company paradigm, with individual corporations in each country to help ease the complications and reduce the costs.

It does not have to employment. Hiring foreign contractors is easier for US corporation than hiring US employees.

It's not really true for the US and Canada thanks to Nafta.

You have different tax withholding procedures, differences in labor law and what sort of employment contracts are allowed, differences in mandated benefits (e.g. parental leave).

This is an issue even if you want to hire in more than one US state.

The question is whether all that adds up to "a lot", which is a value judgment.
