Hey guys, pls, I'd like to find out about the risks I might face for buying a one way flight ticket from Lagos to Moscow with Turkish Airlines as a first time International Student. What I might encounter at the Moscow Airport in the hands of the Immigration officers. There's someone that's kept on telling me to get a Return Ticket. Pls, I need your views from experience. Thanks!
