Midnightblue- In regard to your friend all I can say is that they got lucky, and with the new ETSA system in place they may not be so lucky in the future. And as I learned through my Political Science courses in UNI and through my Law Enforcement friends when I worked in Government, Ignorance of the Law is No Defence...one MUST do their homework before visiting another country no matter how close the ties are between the two countries (IE UK & the US).
I agree, I guess they did get lucky, and I'm sure that now there are stricter checks in place this won't be the case in future.
I also understand that ignorance of the law is no defence and no excuse either -- I want to stress that I'm in no way trying to say that.
And I'm not defending or making a case for flouting the law of any country, but one does have to stop and wonder -- by these standards, then, a great, great many people either visiting the US merely on vacations and shopping trips or even applying for immigration status, would have to fess up to the proverbial apple stolen at age fifteen, or indeed pot still being smoked as a recreational habit -- and face possible ban or at least complications.
I'd wager money thousands are still not being that honest.
By that standard, a huge chunk, far greater than owns up to anything right now, will theoretically have to apply for permission rather than visit on the traditional regular visa waiver. I guarantee you, at least before the stricter screenings came in, that literally millions were blithely entering the US knowing that they don't quite meet eligibility for waiver of a visa, for one reason or another, but they go ahead, have their US vacation, go shopping in NYC, soak up some sun in Florida and go home again without incident -- and also without having run rampage committing crimes....
Again, NOT defending the breaking of laws, but just being realistic in saying that millions of otherwise-upstanding citizens (or even the casual pot smoker, of which I am not one but many are....) with something to fudge will have to apply for visas if following the strict letter of the law...
Having said that, regarding again specifially the law as pertains to a spent juvenile non-violent conviction -- I do have to say, in my opinion, that is a ridiculous law. If the person has done nothing further for 25 years and is now just living their life intending no threat to the country they are visiting, it should be dead and gone, done and dusted as it is in the eyes of the person's home country.
I know that law isn't going to change just because I think it's unnecessary and stupid, and also in fact unfair, but I really believe it is all those things. This isn't even something I personally have to worry about -- I'm glad to say I've lived such a deathly boring life that there are no convictions in my closet, only because Jane Austen's got nothing on me for uneventful living, lol!! But the principal of the thing just pisses me off. Spent should be spent, and 25 years of living within the law should be accepted as the end of the matter.
