If you have changed your address in Kosice, you need to report it to the foreign police within 3 working days. The best way to do it is to prepare a letter, print it, and sign. Then bring in 2 copies to the Foreign police in Kosice (Trieda SNP 35, Košice, 04011) and let police stamp one copy.
How to submit: go to room 220 (Stala služba) and tell, you wish to submit paper. They will collect your passport and RP card and give you a confirmed paper (in case you brought 1 paper for submission and one for confirmation).
If you are living in a different city district (e.g. you shifted from Kosice Zapad to Kosice Stare mesto) – we suggest asking for a new card (4,50€ is the total cost). In that case, fill in the form in RP FORM GENERATOR (form no 4), ask your landlord for a contract and come with RP card and passport to foreign police. You will receive a new card in 3-10 days.
