I was saying that the efforts of past leadership greatly aided to the development of the US. Well, I always expected immigration laws to toughen even before Trump because some section of America was already clamoring for it. I don't think Trump can destroy the strong institutions US has set up over the years.It's true that in the past years USA has been very open to welcoming new folks into their country. But with each government comes its own political policies and D. Trump became the US president, it's been pretty tough to get into USA for most country like Africa countries.
