1. Below is excerpt directly from an earlier post (2nd post in this thread):
b) Identify how you will provide proof of funds
What is a valid form of proof in this case, e.g. do CIC accept a letter of available funds from one's bank? Or is there something else also needed along with this? - Yes, you would need a letter of available funds or Balance Certificate from your bank which states the details of the account held by you, current balance and the last 6 months balance in the account. Additionally, you will need to submit 6 months bank statements.
2. I'm married with a baby on the way. Is it possible to simply apply for myself first and immigrate to Canada and do a separate processing for my spouse and child once I'm in Canada? Note that I qualify in both cases, it's just that there's less paper work to do up front if I just apply for myself. - You can opt to mention that spouse and kid will not be accompanying, but please note that even though, they may not accompany you, you will still need to show POF for all three of you, Medicals and PCC also needs to done for all.
3. Is there a difference in terms of success rate between applying just for myself vs including wife and child in the same application? - I do not have information about the same, but as far as I understand, there will not be any difference in the success rate as long as the requirements are met.
4. Does applying just for myself while disclosing that I'm married have any negative impact on my application? - No, it will not have a negative impact on your application. However, as mentioned above, you still need to complete formalities like POF, Medicals and PCC.
Thanks in advance.
