Why is this hn post not visible?

It was never not visible, but it did set off the flamewar detector, which downweighted it off the front page. We eventually turned that penalty off.

Btw, I've changed the HN title to reflect the article's title now. Submitted title was "Visa holders on vacation have 15 hours to return to US or pay $100k fee". I don't know if the article said that when you submitted it (news outlets sometimes update article titles as more information emerges), or if you rewrote the title, but if it was the latter, please don't do that—it's against HN's guidelines. See https://news.ycombinator.com/newsguidelines.html: "Please use the original title, unless it is misleading or linkbait; don't editorialize."

It is?

Likely because it's too political
