Hello jedrula and tim,
And welcome to the Polish forums.
any advice with regard to everyday life in poland?
I think what you are doing, learning the language is a must.
And living in a city, at first anyway, will help a lot.
I don't know if either of you have ever lived in a country that you don't know how to speak the language but it does isolate you.
Even though most people in cities in Poland speak some English, it is still not enough.
Also just for the common curtsy.
I speak Polish but not as well as I would like, it is hard but not impossible.
Krakow is a great city on almost all levels, i am not too familar with Katowice.
I see some similarities with Ireland but in other ways i see big differences
Yes, Catholicism, a history full of tragedy and alcohol :)
These three similarities has a huge effect, we have very similar sensibilities and humour.
I feel more at home here then other countries I have lived in.
The big difference is what communism left behind. Although communism can be seen as a kind of occupation of the country, the bizarre systems and frustrating bureaucracy is mind boggling to say the least but it continue to change for the better.
Although teaching English is probably the number one option here for English speakers, you should probably try to find something you are interested in (if you are not interested in teaching) but teaching English is not a bad fall back position if anything goes wrong with your primary work.
Also getting some credible teaching certificate can help you in the beginning until you find your feet.
I will stop there, if you have any questions just ask.
Best of luck to you both.
