Some (my English side) on the Mayflower, some ( my German and Irish side) on Wind Powered ships, some (my French side) after living in Montreal for a Century, and the last on a steam ship from Venezuela.
They all have the same things in common. They came here legally and were not a burden on the taxpayers. Many served and fought during the Revolutionary War, the War or 1812, The Civil War, WWI, WWII, Korea and Vietnam. I know of none who burnt a flag, took a knee, or spit on the flag. They all learned English and tried to assimilate into society.
The same should be required of anyone else coming to the USA.
