How come you do not have a Greencard if you were selected for DV? Where did you obtained the visa from?

Why did you apply for DV if you already possessed PR in Canada?

Were you drunk at the new year's eve and only woke up yesterday to submit your papers that were overdue back in July?

Its almost November, are you a Canadian Citizen now?

If you are referring to the year 2011; you can come to US, get the Greencard and return to Canada. Once you obtain Canadian citizenship, its up to you where you want to stay for the rest of your life. If you want to apply for US Citizenship after that, you have to live in US for at least 5 years.
