Law / Query For Permanent Residence in Poland - Can I have two visas? [2]

Hi,

I have been living in Poland for 3 years and I have my work contract until 3 more years. I got recently married and my wife is working in Norway and she is three months pregnant. I want to go to Norway for 6 months and so wanted to apply dependent on her(as I cannot stay continuously for more than 3 months with my current visa in Norway). So, my question is, Can I have two visas (Poland work visa and Norway dependent visa) and will it be a problem to apply for Permanent residence after two years in Poland as I would then be eligible to apply for PR.

Thank you.
