I am planning a trip in Uzbekistan - then a visit do Darvasa and maybe Ashgabat if there is enough time and to then to cross the border into Kazakhstan and fly out from Aktau.
Has anyone done this trip? How easy is it to get a transit visa without a letter of invitation as an independent traveller? Also I have seen that for the transit visa, the Turkmenistan embassy would want proof of visa for the other two countries you are visiting but Kazakhstan does not require a visa so I would not know what to supply for the latter?
Thank you for any advice and info anyone can provide.
