Graham pretty much sums it up.

For what it's worth I met Maria within about a week after I joined an Asian dating site and I felt comfortable about her pretty quickly. She sent me plenty of photo's of herself, and had a webcam and internet at home, and I also spoke with her family. Kind of an ideal scenario.

Give it a go but be patient. You could fall in love with a scammer straight away or you could fall in love with a diamond several months down the line.
