The US has a stupid 50 k visas per year for a diversity lottery where all you need is a high school certificate from any country, not to mention all the illegals from South America There are 60 k H1-B visas where you have to have a offer of employment first. These where gone in 2 weeks when the economy was doing well. Or an investment visa where you have to bring $1mm and employ 10 people. I'm degree qualified engineer, now fulltime trader and I was looking at living in the US for a while and it is very difficult to get a visa. When I would be buying a house, paying tax etc etc all pluses for the US economy. Australia still has 110k skilled immigrants per year for a population of 20mm and with out them the housing market would collapse. They donât need any offer of employment or sponsors etc only the required skills/experience. The US should allow anybody who is wiling to buy a house and shows sufficient funds to be self reliant and who is from a visa waiver country (1st world equivalent), passes security and medical, entry to the USA including self funded retirees.
