Hi,

I plan on visiting Vancouver in the month on June as my friends stay there and we are planning for a backpacking trip cross Canada.
My housing will be taken care by my friend.
I will be applying for a Visitor visa in this week from India.

My concerns are,

1. Do i need a letter of invitation from him?

2. My days of stay are not yet decided. But they are not more than a month. So how can i show the embassy a planned itinerary?

3. I have been to Vancouver,Canada before on a student visa and i overstayed there, as i had applied for another student visa from within country, which was awaiting reply. I didnt hear any reply from CIC so i left canada with no status. I have all the proofs and documents with me for the same. Should i attach these proofs with my current application?

Please help me solve these querries. I dont want to be rejected by the consulate.

Thanks,
Amit
