Kiev is known as the capital of Ukraine. If you have the citizenship of the Russian Federation, and you want to travel to Kiev, you do not need a visa. There is a visa-free regime between states.
Remember that you have the right to enter the country upon presentation of the border guards both the internal passport of a citizen of the Russian Federation and the international passport. Therefore, when planning a trip on a certain date and in the absence of a passport, do not worry. Both passports give you the right to unhindered entry into and exit from the country. The only difference is that if you travel with an internal passport, you will have to fill out a special immigration card when crossing the border. If you have a passport, the customs officer will put you a note on entry / exit, and you will no longer need to fill out anything.
Having solved the issue with a passport, it is worthwhile to purchase tickets.
