The subject lines often read something similar to "From the desk of Mr [name]" or even "Your assistance is solicited".
While the stories may vary slightly, the general plot then talks of a person (usually a corrupt government employee) who has come across a large sum of money and needs your assistance to get the funds out of the country.
Once you do send the money however, it is unlikely that the visit will ever actually materialize.
Instead of asking you to send them money for their ticket, they will instead send you scanned copies of a ticket to convince you they are genuine and are really coming to visit you.
They do not ask for money to buy the ticket or even for visa expenses… However, there is usually a last minute glitch and they will request you to send them a large amount of money without which the trip will be impossible.
Another common scam one comes across in online dating is the medical emergency scam.
Just when you think your online relationship is going really well, your online partner will be faced with some sort of medical emergency.
The money could be cash, gold bullion, blood diamonds, gold dust, checks etc.
The sums usually run up to millions of dollars with the victim being promised a huge chunk of it for their "help".
Variations of these include them needing surgery they can’t afford, treatment for their son’s brain tumor or you may even get a call from someone pretending to be a doctor telling you your partner has been in a serious accident and you need to send money so they can start treatment.
Sometimes, the scams are long and stretched out with the scammers attempting to get as much money out of you as possible by cooking up a variety of medical complications.
These scammers know immigration rules and regulations well and might even cite some sort of visa requirement as their reason for requesting money.
