German Visa
发表 Frank (confidential) 在 德国论坛
I assume you meant "live" instead of "leave" - your English is probably not so good, right?
In any case: Giving an official invitation letter to a foreigner that can be used for getting a visa involves great responsibilities, including liability for all costs (incarceration, fines, deportation, etc.) incurred if the invitee breaks any law in Germany. Nobody in his/her right mind would do that for a stranger from the Internet - if at all then only for very good and trusted friends.
Moerover, you even announced that you will break the law: You want to work and/or school, which is not allowed on a (tourist) visit visa! To do that, you need a work visa (which you can get after signing an employment contract with a German company) or a student visa (which you can get after being accepted as full-time student by a German university - please note that you cannot earn your living besides studying when on a student visa).
For any of this to happen, you need good German language skills (better than your English!). Are you already attending classes? Which level are you at?
