Rules for overseas employment...
1. Don't send any money.
2. Don't leave without a return ticket.
3. Don't leave without a hotel reservation in your name, charged to the airline.
4. Don't pay to be employed.
When companies are short of nationals to employ, they'll pay the price for recruiting expats. If they are not prepared to pay they are not that desperate, certainly not serious and you'll probably end up getting screwed. So before you cough up anything, think really hard - Do these people really want you?
My experience? Well some time ago I was employed by a Belgian company (Euro Direct Belgie NV, part of a company called then called Skyservice based in Kortrijk EBKT). They were bloody marvellous and excellent people to work for.

PS. I've even heard of some scumbags putting out small job ads. so their kids could get lots of lovely international stamps for their collections.
