USA, Canada / Thoughts on moving to Poland from USA [62]

My wife is polish and we are looking to move to Poland . We found a house there and in the process of purchasing it and hopefully have a peaceful life there but we have almost a 5 bedroom house here in LA and like to most of our goods with us.

We have contacted the Cosulate and it seems because of her being Polish , we are free of duty and also found some other information:

I am looking for a good local customs broker in Gydnia who can help with the customs clearence and delivery of the container to our new home? If you guys know anyone trustworthy ,please share the information .

Thank you
