Tell us: have you experienced any issues at the US border recently?

Have you or anyone you know encountered any problems at the border, and are you changing your planned trip to the US?

Following a French scientist being denied entry to the US after immigration officers searched his phone and found messages in which he had expressed criticism of the Trump administration, we're interested in finding out more about any issues that people have experienced at the US border.

Other reports at the US border include a German national, who is a permanent US resident and was detained by US border officials. A Canadian citizen was also detained by US border authorities for almost two weeks over an incomplete visa.
