I applied for a USA visitor visa back in 2018 but was refused. I lost the refusal letter but didn't read it thoroughly and now I don't remember the reason of the refusal.
Now I am planning for a vacation in New Zealand for 7 days in winter 2022, and Question F4 of the New Zealand Visitor Visa application reads:
"Have you, or has anyone included in this application, ever been refused a visa/permit to visit, work, study or reside in any country? [] Yes [] No
And then:
If you have answered yes to any of the questions above give full details. This includes full details of any charges, convictions and the sentence or penalty imposed. Continue on a separate piece of paper if necessary."
What should I do or what can I disclose in response to the question above? I don't want to get into trouble and possibly be banned on deception. I will gladly inquire to the US embassy if they can provide me another copy of the letter I lost.
