If you are seeing a Russian woman and are keen on meeting her, it is always wiser for you to go visit them instead of inviting them to visit you.
Just when you think everything is going smoothly, there is a last minute problem and they will request you to urgently send them some money, without which it will be impossible for them to make their trip.
She will then ask you to send her money for her plane ticket and/or visa.
This ploy also relies on the stereotypical assumption that all Russian and Eastern European women want to move to or visit America, Canada, the UK or Australia which simply isn't the case.
This is a scam and you should never send money for it!
There are several fake website masquerading as Russian marriage agencies promising to bring Western men and Russian women together.
She professes her love and gives instructions to send money through Western Union or Money Gram.
