MY STORY HERE..
Brexit is causing or having so many negative impact on foreign students who do not want to have any future immigration problem with the UK, and indirectly having some negative impact on the British economy, because most British universities will start losing foreign students.
For example, my two sisters and some young members of my extended family studied at Cambridge and conventry university respectively.
About 3 of them finished their Bsc at the time BREXIT came up. Our mom spent atleast closed to 100k pounds from Nigeria to give them good education in the UK after having their diplomas in Nigeria. She always send money from Nigeria in order to give them good education in the UK after they had their diploma's in Nigeria.
What i want to point out is that 3 of them would have loved to continue their education in the UK by enrolling for their master's degrees, which is going to cost mom another 50k British pounds, but those girls changed their minds due to BREXIT and moved to the United States and Canada for their master's degrees.
They never worked in the UK while they were there, they never applied for jobs or takes benefit from the UK government. Mom spent money from Nigeria, pays for their school fees, foods, accomodation and many more in order for them to fully focus and concentrate on their studies, and by that, it helps the British economy. But most Britains always think student who came from abroad always come for their jobs and other government benefits. No, don't be too ignorant.
