Thank Shanlihong for your analysis. Since you've mentioned the so-called way of thinking of foreign officials, Canadians in this case, I think it is necessary for me to say a few words.
It's natural that one will try to verify his or her rightness when something unhappy or wrong emerges. No exception for visa officers. However, the current problem is who's blame to the big mistake in my case. Since January 2002 I had faxed the Consulate many times asking about the issue of visas. But every time the request fell on a deaf ear. So. from beginning to end, the Consulate was aware that I had been waiting for visas. But they failed to take this matter seriously, finally leading to the present impasse. I should say they're really awkward actors. They say visas were sent to me through DHL, but they couldn't show me the mail number; They say they faxed me regarding the status of visas, but we've never seen such an invisible letter; Trying to prove their innocence, they even said I had said we were residing in Tanzania, but, as a matter of fact, my husband only faxed them once from that African country during his business trip, urging them to send us visas as early as possible. While Realizing a big mistake had taken place to my case, they began to act like an ostrich. As the old Chinese saying goes, a quiet conscience sleeps in thunder. But the gentleman in the Consulate seem to be afraid of hearing the knock at the door.
Legally speaking, there is a contract between the applicant and the immigration authorities. Since the Consulate chooses the DHL as courier, it means it should bear responsibility for any fault that possibly arises from the courier's service. As the applicant, my obligation is only waiting for the arrvial of the mail. If the mail is lost, that means the Consulate has not completed its duty and should keep it up. If they say, hey, it's your fault. Why don't trace the mail like a detective? Since you didn't do this, you are blame to the loss of your vias. If that is the matter, I'll say such a way of thinking is nothing but logic of bandits!
Let's return to human's nature of liking to prove his or her innocence. I'll say Westerners are even more outstanding than Chinese in this respect. Actually, they are so stubborn that they always believe they are the truth themselves. Consequently, others' opinion, suggestion or criticism are just rubbish.
If VOs wanna play trick, I'd like to go head-to-head with them. I'll not give up my rights. Never.
签证应该签发在护照上，难道会凭空签发？如果已经交了护照，那就该心中有数了。怎么可能没有递交护照而给签证的，这使馆也糊涂了？ 
，祝他好运！
