The previous poster was talking about the Indian way, where they need a "no objection to immigrate" certificate, for the Indian government.
If the detention is not listed on your husband's police certificate in his country, then it is not listed and will not be discovered by the gov't later on, so you would be safe not to mention it.
Thanks for the clarification, Canadianwoman.
My future spouse is from Dominican Republic. He can get his police certificate same day, I believe, however, in DR there is only 1 police station that the Canadian government will accept certificates for, which is in the capital city.
We are planning to get married in July 2012, and will have almost all of the paper work ready by the wedding and so will finish the remaining paper work regarding our wedding immediately after... I would hope the application would be submitted no later than August 2012.... so we have lots of time, but I want to make sure we take our time with the applciation and make it as perfect as we can possibly make it, since the questions and paper work can be quite confusing.
Thanks again.
