Registering for a country costs money and legal resources, a hurdle most companies are not willing to incur. My hypothesis is that people are naturally lazy, so they find the easiest path. If recruiters know they have to go through extra loopholes and paperwork (if they don't have a system set up already), your likelihood of being hired decreases significantly. They won't admit this (illegal discrimination), but it is human nature.
