Summary

Germany updated its travel advice for the US after three German nationals were detained despite holding valid visas or entry waivers.

The Foreign Office clarified that holding a US visa or ESTA approval does not guarantee entry, as border authorities have the final say.

Recent detentions include a green card holder held at Boston airport and two others detained at the US-Mexico border.

Germany investigates whether these cases reflect a broader policy shift under Trump’s tighter immigration policies.
