I can guarantee you that being in Poland for a holiday is completely different to living there.
I can second that , albeit if you move to the right place you might be amazed how many other expats have moved in to Poland and generated a circle of friend that may be able to help you along the way,
Although I would be classified as living in the sticks you would be amazed by the number of English, Australian and dutch partners that have moved into my area .
visited his home city,
Can I ask where that is ?
