At my old company, we engaged with a contractor from France. We went to university together and I knew he was well qualified to do the work we needed in OpenCV.

At my old company, we engaged with a contractor from France. We went to university together and I knew he was well qualified to do the work we needed in OpenCV. We researched ways to pay him legally, but for a six month contract it turned out to be much easier to simply pay an agency that pays him and does the paperwork. Essentially it is presumed that most workers are full-time employees, and it is difficult to maintain a contractor due to tax liability and labor laws.
