JD Vance and Usha Vance left Switzerland on or after June 20, 2026, but the sources I found only clearly show that they arrived there on June 20–21 and were heading into talks, not the exact departure time. One report says they arrived at Emmen Air Base outside Lucerne just before 6 a.m. local time on June 21, 2026, and another notes Vance was departing for Switzerland on June 20, 2026.

What’s confirmed

  • They were in Switzerland for U.S.-Iran talks in Lucerne/Bürgenstock.
  • A June 20 report said Vance was en route to Zurich, Switzerland.
  • A June 21 report said Vance and Usha Vance arrived just before 6 a.m. local time.

What isn’t clear

The publicly available reports I found do not give a precise time for when they left Switzerland.

TL;DR

The best-supported answer is: they left sometime after the June 20–21 arrival window, but the exact departure time hasn’t been clearly reported in the sources I found.
