After a historic agreement, the border between Arstotzka and Equestria will open, allowing the citizens of these two parallel universe to travel from one world to another.

Will these two words be able to coexist?

And above all...

How much can the events be influenced by the decisions of a simple checkpoint's Inspector?

This will be a crossover between "Papers, Please", a game developed some years ago, and "my little pony"

September 7th, 1986. Equestria arrives on Earth and declares humanity 'evil' and 'unfit'.

September 16th, 1986. Talks between the races begin.

Quickly, the Soviet Union and the United States are forced to join forces to save humanity.

For some of the humans this could be a godsend. For many, however, they know what they have to fight for.

The humans know that they can only win together, and they will have to unite in order to prevail.

A/N: This fic will mostly be pro-human rather than pro-conversion.

The humans have travelled to Equestria to share their knowledge with the ponies. However, what the human scholars bring with them quickly turns out to be a bit much for the simple-minded locals.
