If you buy a ticket for a match of 2018 FIFA World Cup Russia, you get a Fan ID and can use it to enjoy visa-free travel to Russia. Do you have to attend the match as a condition?
I am not a football fan (sorry) but I am tempted to buy a last-minute ticket and use it for a quick Russian tour without going to the stadium. Is this acceptable to the Russian immigration authorities? One obvious downside is losing $210 (or whatever is the cost of the ticket).
I have seen this question, although the titles are similar that question has a different situation.
