My family member has their interview coming up.
They submitted their DS 260 July 2020. In September 2020 they were turned away from the US Canada land border due to Covid essential travel rules. They were recommended at that time to try traveling by air instead.
The concern is on the DS 260 in July 2020, they responded that they were never denied admission which was true at that time.
My question is how should they respond if asked if they were turned around at the US border at their interview?
