[astatine]

A good, friendly site for this info is much needed. But, as many have pointed out, this is a particularly tough problem to solve as the source of info is itself unreliable.

I checked India to eSwatini and was not surprised to find that the country was still listed with its old name, Swaziland. The visa situation for this pair is complex with a visa preapproval that's needed and a visa to be obtained in eSwatini not at the border but at an office in the city (which you are allowed to go to). And, naturally, none of this is documented anywhere.
