"A number of developed countries have implemented guest-worker programs in recent decades. Its basic feature is the temporary presence of the foreign guest-workers. The problem with such programs is that there is little to prevent these guest-workers from entering the illegal job market and overstay their legal welcome, which is the reason why these programs became unpopular over time.
