Relocation on an international could cost up to a few thousand dollars depending on where it is that you wish to relocate your workers to, and the degree to which you need assistance with this. Also, right now it is harder to make mid level and senior employees move, thanks to the fact that they may be well settled with their families where they reside at present.   

One of the most important things that should be on your mind when attempting to relocate your employees on a global level is to make sure their visa paper work is all in order. Be warned that different countries have their own processes and different mechanisms to hand out worker visas, so that may need a little bit of research from your part.

Of course before you can move your employees you will need to find the right specialist or person to assist you with all this paperwork, and here you need to begin looking. Unfortunately there is no such thing as a global newspaper to look into the classifieds, but the internet is close enough to that. You could look online for the right company to assist with relocating to whatever country it is that you have your eyes on. Hire a professional that has offices in that country.

Once you have the candidate list for relocation at hand, you need to make them an offer they won't refuse. Most people don't like being relocated, and they definitely will not accept your offer unless it gives them a higher salary and benefits.

If you are sending your workers from an eastern country to the west, they may need a few spoken English lessons and so on. That will ease them into their new homes and help them gel well at the work place as well. Communication is after all one of the biggest factors that effect work quality. The right relocation specialist should consider all of the above mentioned factors if he truly means to take the responsibility off your hands.
