If an EU citizen intends to stay in the territory of the Czech Republic for a period exceeding three months, he/she will be entitled (but not obliged) to apply to the police for a special residence permit (temporary residence permit). The issue of the said permit is not a condition for the stay of EU citizens in the territory of the Czech Republic, irrespective of the purpose of the stay. On the other hand, it has benefits for a foreign resident in situations where proof of a Czech address is required, e.g. for some rental and purchase agreements. If the application is handled affirmatively, the police issue the EU citizen with a permit card Průkaz o povolení k pobytu státního příslušníka členského státu Evropských společenství (cover in purple colour). Citizens of Switzerland, Norway, Liechtenstein, Iceland and their family members who are not EU citizens will be issued by the police residence permit cards Průkaz o povolení k pobytu (cover in green colour).
