Hi. I am a citizen of Poland. How do I answer the question on 'have you ever been refused a visa to any country?' if I am actually not sure. Over 25 years ago, I went to the US Consulate outside of Poland and asked for a tourist visa but they told me that I could not do it, as I should have applied from my own country. It was so long ago and I was very young and did not understand immigration systems at all, so I really do not know whether they actually refused my application, or whether they just gave me an advice not to bother to apply. I should only asked that later in life I got multiple US visas (in fact I have one valid B1/B2 visa now). What should I answer in my Canada eTA application? Should I say 'yes' or 'no'? There is no 'I do not know' option.
