Legal risk, unfamiliarity with the remote job market, cultural differences.

Some companies might no have the internal legal frameworks to hire remote in the US or far less outside the US, as an anecdote a company I used to work for was fully remote but only hired remote on some specific states, this because of tax laws that would vary in each state would complicate their operations. This was a smallish company, less than 40 people.
