If we consider the better way to date FSU women, the best way is to enter in their territories.
Olga an I have talked about the territories outside the mainland,
but if we talk about the mainlands, what happens?
The truth is that the war has disrupted the aerial traffic.
There is not traffic at all in Ukraine
And the traffic in Russia and Belarus is cut from direct flights, but not impossible using hubs.
The main hubs are located in Istambul, Belgrade, Bakou, Tbilissi that allows you to enter in or enter out.
So the strategy to rejoin the mainlands is suffering, due to the war, to stretched delays and increased costs to enter in and out.
In Ukraine basically the main hub is Poland where your plane is gonna to land in Varsaw or Cracovie and then you take the train to the border. Then after you enter in the Ukrainian railways infrastructure. You are good for at least 24 hours of trains and connections not counting the flights
Good to know, using a car from Europe let you without insurance as you cross the Ukrainian border. Even moving to Moldavia (I tried to rent a car there) let you without insurance (maybe it has changed, because it was ridiculous).
In Russia it looks like a little easier but as it's a very vast territory all depends on where you go.
More than never, in case you are chasing a girl to marry her in USA or Europe you damned better to choose first a big city, and after to chase the local girls in this city, due to the war context.
Of course more difficult to go, but more rewards as men become scarcity, especially in Ukraine
If you play the nomad mode let them know that you come to spend some time. Some will be curious and very pleased and some will be totally pissed off. The last ones let you know that were mainly interested by emigrating. Good to know.
