Hello, I am a non-EU citizen and I was full-time student in Poland (I don't need work permit in Poland.) My resident permit (short term - Karta Pobytu) was issued based on work on November 2016 and it is valid for 3 years. Recently, I have changed my job and I am not sure if I need to apply again for resident card or even let the office know about it. - I wasn't unemployed while I was changing the job - My contract is the same as before (permanent) and salary higher than before - As I didn't need work permit, name of employer is not mentioned in my decision. Thanks for your time, any help is appreciated. Best regards, Maryam
