It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that
In the vent if you plan to fly to Ukraine from UAE and that you have to do stopover in the Amsterdam's Airport,
Then tou'll need a transit visa that's because you are traveling to a country which is not part of the european union, so when you transit via a european country member, then you'll need a transit visa.
You can get the transit visa from the Deutchland (holland) embassy.

In the event that the intended question is otherwise, you can kindly ask us in detail and we will respond to it in the shortest time frame.
