Help me to get some informations

Friends, please furnish me with some information. I need to know the followings:
a. What is the prospect of an Army Officer (male) and kindergarten School Teacher (Female) to get immigrant visa in countries like Canada, US, Australia and New Zealand.
b. Which province is better for a livelyhood for a resident of Indian Subcontinent.
c. Is there any web site which can render guidance in real terms (not the official web sites please)

Regards
Rahman

For the US, it's very low indeed - unless there's something else you haven't told us.
