This question has come up before and I believe the answer depending upon company and whether it was employment or contract. In my experience, it's flexible. But consider that companies have their own legal departments, advice, and tax requirements that may make the decide on hiring only people in their own jurisdiction. Technically yes they could all hire whoever they want as an independent contractor and make the bank transfer but that's too messy for many of them.
