Hi there, how have u been?

I just have a quick question again...if u dont mind, that is..

We have already applied for the residence and work permit here, we will get the result of the application in 5 months, but funny thing, they didn't ask for my boarding pass in the plane, is that ok? How would they know when was my first initial entry in Norway then?
My second question is, recently, the health office here called our house to tell me that I should undergo a Tubercolosis (TB) examination. She said its required to everyone who has just newly arrived in any country in Europe including Norway. And she said I should do it within 3 months of my stay and on Christmas day, will be my 3rd month here. Is there really such a thing? Did they required ur wife to have a TB-test too when she was still new in France? Im just wondering cause we were never told about it by the local immigration here. All of a sudden, the health office called our house to tell me I should have a TB test. Im not really that worried though but I was wrongly diagnosed with TB by some filipino doctor 3 years ago, when he saw my Xray. But we didn't believe it so we asked for another doctor opinion and it turned out that I have no TB at all. Should I tell the health office about it?

Any insights u can give will be highly appreciated. Thank u so much.
