I got letter from a woman called herself {personal info removed}. She said that she has paid money in internet café for the manager and he gave her my email. Since then she started writing to me. We have been exchanging letters for about two month. Now she wants to come to visit me. The thing I am worried is, she asks me to help her for air ticket, how could I trust her whether this girl is honest or it is true what she is saying.

Tell her you will reimburse her when you see her.

Sorry to tell you, it's a scam. She is probably not even a she at all and it is all about them wanting money from you. You will be asked for money for a plane ticket... money for a passport... money for this and that and whatever until you have no more money to give. You will never see this person. All you will get out of this is heartbreak and an empty bank account.

Trust me... stop communicating with them and save yourself the pain.

Where is she from?

Why would you spend any money on someone you don't know? STOP this and get your head plugged in right.

This is a fairly popular scam,

This is a scam, and if you have been sending letters with your return address, keep an eye out that they have not opened any credit accounts in your name.

Check your credit often.
