Due to the lack of border control at the internal borders of the EU (including the border between Poland and Czech Republic), at the time of crossing the border, the legality of the border crossing will not be verified. However, the legality of a foreigner’s stay may be checked at any time already on the territory of the Czech Republic.
Council Implementing Decision (EU) 2022/382 of March 4, 2022, establishing the existence of a mass influx of displaced persons from Ukraine within the meaning of Article 5 of Directive 2001/55/EC resulting in the introduction of temporary protection applies to the following categories of displaced persons who had to leave Ukraine as of February 24, 2022, as a consequence of the military invasion launched by the Russian armed forces on that date:
a. Ukrainian citizens residing in Ukraine before February 24, 2022;
b. A stateless people or third-country nationals other than Ukraine who were under international or
equivalent national protection in Ukraine prior to 24 February 2022;
c. Family members of the people mentioned in points a) and b).
The above-mentioned people have been granted temporary protection in the EU countries, hence in Czech Republic as well, which opens the way for these foreigners to enter the territory of the Czech Republic and stay legally in that country, or to apply for international protection.
Temporary protection is generally granted for a period of up to 1 year with the possibility of extension. Protection is also provided for stateless people and third-country nationals other than Ukraine who can prove that they have resided legally in Ukraine before February 24, 2022 based on a valid permanent residence permit issued in accordance with Ukrainian law, and who are unable to return to safe conditions in their country or region of origin.
As for the remaining foreigners who are not citizens of Ukraine, EU members may also grant temporary protection to all other stateless people or citizens of third countries other than Ukraine who have legally resided in Ukraine and who are not able to return in a safe and durable environment to their country or region of origin. Such people may include third-country nationals who, at the time of the events leading to the mass influx of displaced people, studied, or worked for a short time in Ukraine.
The purpose of such protection, however, is not to legalize the stay of such a person in an EU country permanently, but only to enable them to travel safely to return to their country or region of origin. Therefore, the possible longer stay of the Indian citizen named in the question in the Czech Republic is governed by the national regulations of the Czech Republic and requires verification in the Czech legal system.
