The primary difference between professional expatriates and virtual expatriates is that

professional expatriates can avoid misunderstandings that arise from cross$-$cultural communications.

for virtual expatriates, building close contact with customers is much easier.

professional expatriates do not incur any extra expense to the company.

for virtual expatriates, establishing a good working relationship with subordinates is much easier.

virtual expatriates work from their home branch and do not relocate to the assignment country.
