I just submitted application for DTV Visa in Vancouver Canada consulate, called to make sure I had all the right documents, including a letter I wrote explaining all my business activities, the person on the phone said it was OK to write your own letter explaining all your business activities and that my business was online/digitally, he also said it would not take longer than 2 weeks, others here have said it took 2 business days, so after I get my DTV I can apply for my wifes, with her banking information and our marriage certificate, hoping all goes well
