I may agree, but the 14th Amendment is worded in such a way that you really have to do mental backflips to interpret it as he wants to.
I have been told that. As I understand it there are just two simple definitions in birthright citizenship:
1-By virtue of the person's birth within a United States territory.
2-Because at least one of the parents was a US citizen at the time of the person's birth.
I suspect that in all likelyhood we are, once again, witness to Donald Trump making demands that would require a huge rewrite of the amendment but in truth, seeks to close the known loopholes. I only just looked but there is a staggering number of different nonimmigrant visas. I was really surprised.
But it seems that 'birthright tourism', temporary workers and those present within the US with no valid visa represent virtually all of the cases. I don't know for certain, but those appear to be the three catagories where data suggests a significant number of births. It's certainly the ones the media mentions.
I have to say, I was shocked at just how many different types of non immigration visa the US issues. I'm uncertain why a physician would be in a different catagory from a professor (for example).
It just seems to me that a lower-key announcement that included a full explainatinon of the proposed changes would have been more constructive. I have a friend, a computer game developer. He and his wife moved to the US many years ago with his having 'a speciality occupation in a field requiring specialist knowledge'. But at the moment, couples in their position can't plan to start a family or, at least, the non-specific announcment adds an extra unknown.
I forget who said it but one former US president remarked 'You campaign in poetry, you govern in prose' which I take to mean that on the campaign trail, it's reasonable and expected for a candidate to paint a picture of their vision in broad strokes so voters understand, but the constitution with it's amendments, federal laws, state laws, interstate compacts, international agreements and so forth. It wouldn't be possible for ANY candidate to be aware and even less fully understand them all.
That said, even before taking power, isn't there a two month gap between winning the vote and inauguration. So don't those two months at least allow major campaign promises to be detailed to ensure they are fit for purpose?
I ask as an outsider. I have tried to understand but sometimes it can be quite confusing.
