My wife and I come from Brazil and are currently in Slovakia due to her work. She has an Italian passport and by the end of the month, we both should have our EU residence permits issued in Slovakia. I found a job in Poland where I will be paid in a B2B fashion. I would stay between 3 to 4 days per week in Slovakia and 3 to 4 days per week in Poland. Is it better to open a company in Slovakia or in Poland? Which type of company am I allowed to open? Thank you,
