All EU or EFTA students are legally obliged to register with the Foreign Police within 30 days of their arrival to the Czech Republic, if their intended stay is longer than 30 days. All citizens from non-EU or non-EFTA countries have to register within 3 days. To register, you must present a completed form for the Registration Card, a travel document and evidence of health insurance (e.g. European Health Insurance Card).
If you are staying in Charles University Hall of Residence and intend to stay there for the full time of your studies at Charles University, you don’t have to report your presence to the Foreign Police unless you need a confirmation of your registration. The accommodation office of your Hall of Residence will register you automatically.
