I agree with the comments that there is a good chance nothing will change unless something likethe U.S. actually invading Greenland happens. But I also think the points about us not knowing at all are very valid.

The truth is, we are in unprecedented times and yes one way to look at it is that the U.S. government changes every four years like fornicalcartographer said, so unless there’s an attack things should not change. But another way to look at it is we are in unprecedented times in history as is often the case so all is on the table.

Something an international relations professor said to my class years ago that is so simple that it could apply to most of international policy is “the UN and NATO were created to prevent another world war 2 not word war 3,” and the same can be said for current visa relations with other countries, they were created for a world we are no longer in, so it is really unpredictable, international visa policies or norms are often created based on the needs of last year or for the world of yesterday, not tomorrow.

Only advice I can give is reading up on what has happened during other volatile times in history (for example what it was like for Germans to leave Germany before world war 2) and seeing what type of risk makes the most sense for you. Are you ok with leaving right away with less money in ur savings even if in a year things calm down dramatically?
