Extending stay.

Oh yeah I forgot to mention I am on a Visitor visa and from the US.
On my first arrival they gave me a VR for 4 months so I applied for extension and asked for one until January 31st and got it.

Just thought that bit of info might help.

So would our statutory declaration of common law union suffice when we mail the application?
We already have that signed and more than likely won't be able to marry until the extension is being processed at which time we would have proof of the marriage.

So would pay stubs, bank statements, and letter from employer work when showing that he can support me?

Thanks for your advice. It truly helps.

Oh and do you know where we could marry civilly in Newfoundland and how long it takes to get a certificate?

What if we do get married before sending the extension but don't have the official certificate yet?

What could we provide as proof then?

And would it be alright if it is just a copy of the receipt showing we are in the process of putting our application together or does it already have to be in process by the time you send the extension?

Just want to make sure I am going about this right. Would definitely prefer it not to be denied.
