Hello Singapore777,
welcome to this forum and congratulation for your decision to get married.My opinion is go and get married.wait for AOR form SVO.
In your AOR it would be mentioned the followings:
You must notify CIC of any changes to your application. Examples of changes includes:
• Changes in your personal circumstances, such as birth or adoption of a child, a marriage or a divorce
• Change of your contact information(e-mail, mailing address, telephone number)
• Decision to withdraw your application
By this time you can arrange the following things:
* Marriage certificate
* Passport of your Spouse
* Birth certificate
* Educational Certificates
* PCC
* Photographs
I wish this information may help you.
Best Regards,
