Thanks david.
One more question.What is the maximum duration for which I can get a visitors visa? I am 7 months pregnant.
Is it possible to get an extension for the visa after i reach canada?
Also can I apply for a work permit after I reach canada?
I want to give birth to my child in canada. Is it possible for my child to gain citizenship? My husband has a 1 year work permit visa.

Thanks Purvi
