its a big step
It sure is... that why I saidm first take a small trip to Poland. See the conditions, if it suits you, then stay ofcourse.
I know our economy is improving, but not so much like USA. Actually, prices are increasing more than the capacity of people I feel.
You have good experience, you husband can find a job too... but my guess will be that you will have to work harder here, and the pay might not be as good. But my guess, or anyones guess...cannot be the basis of such a big step can it? The future of your family, children... so much depends on this :).
Take it easy... think about it. And ofcourse... tell me what happened... it will be nice to know!
