You've never been burned.

Hiring foreign employees is a lot different than hiring locals. Depending upon the country, sponsoring a visa can cost a lot of money and, more importantly, a lot of time. That lost time takes many forms. You'll have reams of paperwork. You may have interviews with immigration departments. You may need to find and/or furnish an apartment. You may need to spend weeks holding the new hire's hand after he arrives, teaching him how to deposit his checks in his new land, buy groceries, etc. And you may need to set your plan in motion months ahead of time to keep the organization running smoothly.

So when you invest all that time into bringing someone on board, and then they just quit shortly after arriving ("LOL broke up with gf seeyaltr"), it hurts. It hurts bad, for months, while you scramble to find someone else. And it's not the kind of mistake you make twice.

Without understanding exactly how it works in Denmark, I can nonetheless understand an employer's reluctance to subsidize a foreigner's love life.
