Dear brother

dont worry, I was also given the technician designation, it has nothing to do with ur visa, only you need to have ur salary certificate and visa application form, house electric bill, marriage certificate attested, and children birth certificate if any, and also your degree certificate fotocopy attested thats it what you need. I got my wife and daughters visa just yesterday. dont worry man, dont listen to anyone. just do  what I said, if you need any help PM me and I will gve u my mobile  number so you can talk to me.

Regards
