There definitely is a lot of Nepalese students here these days. That's for sure because I have seen a lot of them, all coming in around the same time this year. Most of them haven't got jobs for more than three months now and I have seen it as well.
The remaining, I've heard as well but not seen and the people I heard it from heard it from someone else who heard it from someone else and it goes on.
Someone changed the whole course of my life because they heard something about me and went on to tell someone else who went on to alter the story and tell someone else who altered it a bit and told someone else and so on and when it finally came back to me it was absolute nonsense that devastated the path I was in with no fault of mine. So unless I actually see something, I don't believe a word I hear from my fellow Nepalese.
I'm sure Khattammanchay must have heard this story about Nepalese Students in UK from someoneone who heard it from someone else.
