I read another thread about flagpole landing and how you are denied entry to US but that it has no effect on future trips. This is what happened to my husband, we were told he was "denied entry" for the purposes of processing his residency in Canada. The US official said it was so that if Canada found something was missing in terms of documentation they had to keep him in Canada. He told us it would have no effect on future travel and that we could try to cross the next day and everything would be fine. He did say, however, that if we were ever asked if he was denied entry, we would have to say yes and explain. He gave us a form we had to give to the Canada official when he went to land. I was ok with all of this at the time, but we now need to travel to the US for a wedding (in a few months) by car. Since he is from the UK he is from a Visa Exempt Country. However, I found a website that has a wizard that does the analysis: http://www.consular.canada.usembassy.gov/ . One question is "Have you ever been denied entry into the United States?". If I answer "yes" it says he needs a visa to travel to the US. If I answer "no" he doesn't and would just need to fill out a Form I-94W at the border (which I also know asks if you've been denied entry). I am wondering if this "technical" process where they had to deny entry constitutes a yes or no answer to this question. I know that to fly to the US he would need to apply through Electronic System for Travel Authorization (ESTA) https://esta.cbp.dhs.gov/esta/esta.html?_flowExecutionKey=_c81BB7D95-9A42-6DF7-3273-92F24FB7A92B_kBC9F28E2-BB34-9B8B-58CC-5C4C8A02EBBF, where it says if you've been denied entry before it's almost 100% the ESTA application won't be approved. If he does need a visa, we will need to apply and make an appointment, but will also need a copy of the incident report, which I'm also not sure how to get. We are concerned. Any advice in terms of this? We don't want to get to the border for the wedding and be denied because we've missed something. I've also read about getting an entry waiver. But since the "denial" wasn't for a reason, really.
