How do British students apply for immigration?

You can apply for high-tech immigration in Britain. I just managed to get a visa myself. The embassy will grade you according to your age, income 1 year and your experience in studying in the UK. My score is exactly 100. I came back from my master's degree in England and worked for three years. The embassy only looked at my work income in recent 1 year, which was as high as 1 10,000 yuan. But I made the materials myself. Hehe, it saves a lot of money. Do you have any work experience? This is very important.
