I'm planning to fly from Europe to Minsk on 29 September, fly out from Minsk to St Petersburg on 1 October and go back from St Petersburg to Europe on 9 October with a layover (2 hours) in Minsk.
As I'm in a possession of Russian single-entry visa for my stay there, I have some doubts about required visa to Belarus. From what I see, "5-day visa-free regime" does not apply to me as I go to Russia directly from Belarus. But in this case, which visa is applicable for me ? Is single-entry visa enough taking into consideration my layover when going back (even though I won't leave the airport) ? Or should I apply for double-entry visa ? If the latter, how to overcome that my visa invitation letter states only 2 nights in Belarus ?
I will be using European Union passport but I have a residency outside EU, in case it makes any difference.
