Hi,
Timatic is an official service provided by IATA. All the airlines companies use it for boarding. It's official and very useful.

I know that the link above is a Star Alliance link but it's the manner to use it. In the past, I used it on the site of …Kenya Airways but since few years I use the link above.
You can also check with the site of the Tajik embassy (Brussels for example). They provide reliable informations.
