Non-EU Citizens
Students should have a valid passport and student visa.
Every foreigner who is not a citizen of a country with which the Republic of Poland has concluded an agreement on the abolition of the visa obligation must apply for a visa in advance in order to enter the territory of the Republic of Poland. The Polish Consuls are authorized to issue visas outside the territory of the Republic of Poland. The visa you will apply for, permit a foreigner to stay in Poland no longer than 6 months within a period of 12 months.
If you are planning to stay more than 6 months (in case of visa holders) or more than 3 months (in case of those who do not have to apply for a visa), instead of prolonging the visa or applying for it, you must apply for a temporary residence permit. The formalities usually take a longer time, so it is highly advisable to take care of them as soon as you arrive in Poland.
