Specifically on the DS160 application there is a question that asks "Have you ever been removed or deported from any country?"
If someone was denied entry to some other country at a port of entry, would that fall under either term?
As much research that I've done into the definitions, the best resource that I could come up with was the answer to a related question here Difference between deportation and removal Which indicates that this case would fall under removal, but again this is under UK law. Alternatively, other sources suggests that being Denied Entry is a distinct category and the application itself seems to specify "Entry" as distinct in other sections.
I can't seem to find a clear answer from any source regarding this issue and I would greatly appreciate any help in resolving this issue.
I will note that, to err on the side of honesty, it's probably better to write this down anyway as it and let the consulate official come to their own decision.
