Several weeks later the victim looks at their credit card statement and sees billing for adult chat services.
In this scam the scammer asks you to send money for fees for college, university or other educational activities.
Shortly later they will tell you they need additional money for a passport, visa fees, transportation to the airport and miscellaneous expenses.
In some cases they will also tell the victim that the visa requirements state that they need to have a certain amount of money in their bank account so they can proof to the immigration official that they have sufficient funds for their visa.
Remember the golden rule - NEVER SEND MONEY TO ANYONE YOU MEET ONLINE.
