I understand you, it's not that sense of "should" I mean. The "should-ness" I mean is that the line reads that there's an implicit understanding that a dual national will have both passports and that at this point having two doesn't jeopardize citizenship. The letter is awkward because completely unnecessary. When we apply for a driving license, do we expect the DMV to call us at work and remind us that having a license may increase our liability when we drive? No. So why the call? For whatever reason the civil servant made the call, it must be understood that having an official of the State call a citizen has a chilling effect. Especially in an age when the Home Office is doing sly and disgraceful tactics like calling in asylum seekers "innocently" and then essentially kidnapping them and placing them in detention.
And, to underscore my first point. Since when is it the IND's job to mediate State department concerns?
While my case and wishstar's weren't identical in that we didn't mail them on the same day, they were identical in that sfgirl got a letter, wishstar got one, and I didn't who came in between them. I did get my US passport mailed back in a thin second class envelope that made it obvious that it contained a passport, which shows how much the IND really cares about other states' documents.
btw, Garry, is it really true that there's no requirement for a UK dual citizen to enter on the UK passport?
