Unemployment and workers problem

Now a day many important things can be solved online. People can post job and take interview through net. But the only problem is visa. I think if any company decided that they had got the right person from other country then should be able to bring that person in their country with family. Here visa process should be easy. Then it will be very good for the companies and also for the job seekers. Unemployment and workers (short of worker) problem will become very less. Companies will be able to bring employee from those countries where they have more skilled people than the work.
