I am planning to visit Northern Poland and then Lithuania, Latvia and Estonia. I am thinking of going into the Russian state of Kaliningrad as well. I've read that compared to Russia proper it is easier to get a three day tourist visa for Kaliningrad. You don't need an invitation like for main land Russia.
I have a German passport and will leave from Berlin in the next few days. Is it possible to get a Kaliningrad visa in Gdansk or Vilnius in a day?
