Can you change your name in Poland without a citizenship?

My friend is moving to Poland soon and wants to have his name changed but can he do that without a citizenship? He will apply for a permanent residence in Poland but won't have citizenship for a while. Would he have to wait to have his legal name changed until he has a citizenship?

your friend has to change his name changed in the country he is a citizen of first.
later, if he becomes polish citizen, he can change it here in USC
