The intense media focus and scrutiny on Melania Trump’s immigration status in the 1990s brings up a good point that Donald Trump, the GOP presidential nominee and Melania’s husband, doesn’t seem to realize: Immigration is not the easy black-and-white issue he’d have us believe.

Here’s the story: Melania has said multiple times that while working as a model in New York City she had to fly back to Europe “and stamp your visa.” Experts that Politico spoke to say the type of visa Melania must have had that required such frequent trips back to Europe must not have been a work visa. We don’t know for sure because the campaign isn’t releasing details (maybe they can’t track them down, or maybe Melania doesn’t remember specifics).
