I am a retired engineer with close connection to the high tech industries. In my entire career, I had never encountered a single illegal immigrant in IT. All the Indians, Chinese, and Russians I met were either American citizens born in the US or legal foreign workers on H1B visas. What I would like to see is that more native Americans will enter the IT and high tech sectors. They are the first immigrants. All of us came after them.
As for the Brits, consider these two facts. 1) They had invaded and conquered 80% of the world before the end of the 19th century. Remember the empire on which the sun never sets? And now they have descended into a clan of immigrant phobic islanders (to be fair, only 52% of them). 2) The USA is a nation of insurgents of immigrant descent who revolted against their British overlords.
