I'm taking a train from Germany to Russia and back. In both directions, the train is direct at least between Poland and Moscow. On the Belarus transit visa application form, question 19 is:
Тэрмін дзеяння візы / Dauer des geplanten Aufenthalts
with three subquestions:
з / von
па / bis
на тэрмін знаходжання / Anzahl der Tage
What do I write here? On the way east the train arrives at Brest at around 21:15 and departs between Orsha and Smolenks between 05:30 the following day. On the way west the train crosses between Smolensk and Orsha around 20:30 and then leaves at Brest around 05:10. I'll be in Belarus on four days in total. Does that mean I should write 4 for на тэрмін знаходжання? Or should it correspond to my Russian visa (plus two days), such that e.g. westbound transit on September 1 and eastbound transit on September 20 would be a transit visa valid for 20 days? I find the idea of a transit visa for 20 days confusing because transit doesn't take 20 days — it takes 1 or 2, in each direction...
