A novel enforcement push that's bad news for thousands of Argentine parents behind on child support, and a publicity win for the government.

• Buenos Aires gave US authorities a list of 13,000 Argentine parents — mostly fathers — who owe court-ordered child support, asking that they be blocked from 2026 World Cup stadiums.
• The argument: anyone who can afford flights, hotels, and match tickets abroad can afford to support their own kids first.
• It looks more like a publicity stunt than a binding rule — the US is under no obligation to enforce another country's request, and there's no sign anyone was actually turned away.
• The move fits the Milei government's image of pushing personal responsibility, and is being framed as public pressure rather than real legal force.

Outlook: Expect more naming-and-shaming than actual stadium bans, with the real test coming if fathers get flagged on their return home.
