Thanks Charlie for your thoughtful insight.
I'm going to venture the opinion that one of the things they are looking at is the short length of your courtship, - yes, this one is an issue as well - and maybe the fact that overall since you've been married you may not have spent a lot of time face to face with your spouse - 5 weeks total so far-, and don't seem to be making any effort to combine your lives - we both have jobs, I have only a limited number of days per year for vacation, I have a son in University for which I am directly responsable, he is in my custody, and I pay child support to my ex for my daughter, giving up my job is not an option here. This gives the impression that the marriage is not meant to last and you are avoiding emotional and financial "entanglement" to make it easier to separate once the visa is in hand.
When selecting chat records and emails to send, don't just pick days at random, LOOK at your conversations and choose actual dates when you discussed matters that demonstrate financial and emotional interdependence. - I did just that, I have chosen three records from each month, and many of those were hand picked showing some relevant discussion we had regarding our future together, planning our marriage and wedding party, and so on, discussing how we would handle our finances together, chosing new furniture for our house and so on...
Also we make many day to day decisions together, how we plan our lives on a day to day basis, we talk daily at least once.
Charlie, I got your points and I will make sure we have all those for June.
Thank you very much.
