The difference is that investors, as a rule, don't work directly for the Federal Government. Customs and Immigration officers do. Do you want to know, pretty much exactly, why we're seeing incidents like this? Because some time pretty close to the day Trump was inaugurated, a memo went out to people involved in handling immigration that used words to the effect of: We're going to starting Cracking Down on.... followed by a list of categories of people for immigration officers to look out for. And it almost certainly included people who had recently been to Iran. Hence the detention of the former Norwegian Prime Minister. And it almost certainly included people who might be "sneaking into the country" under a tourist visa and taking jobs from American workers. We've all seen that "cracking down" phrase used in our lives. And most have seen it abused and misused by that subset of idiots among the people charged with doing the "cracking down."
