1.德国留学生怎么发邀请函德国一般是要求原件的，电子版的有可能会被要求补材料，当然也不一定，可以试试运气 。存U盘就没必要了，还不如找个彩色打印机打出来 。
然后你还需要写一个在德国的行程安排，就是哪天在哪里干什么之类的，相应的酒店要订上，房间订单要酒店发传真给你 。
你还需要你现在学校的同意书，就是准假证明，或是放假证明也行，表示在假期里 。
其他的就是经济类的证明材料，要看签证官要不要，最好准备上，表示你只是参加个考试，不会非法逗留，你在德国期间的费用可以自理等等 。

To whom it may concern,
My name is Zhang San ( Passport No: G16012345 ), I am currently a full-time registered post-graduate student studying Biology at Heidelberg University.
I have lived in Germany for more than 2 years, and I have not seen my girl friend Li Si ( Passport No: G16054321 ) for more than one year. Therefore, I miss her more than I can say, and she misses me in the same way. That is why I am writing this letter to you to invite her to Germany so that we could both enjoy a marvelous time together.
I wish to invite her to visit and stay with me for 17 days or so, that is from March 20th to April 5th.
Besides, I live in a house with 45 square meters in area, which is more than sufficient for us to live in.
I hope she can come to join me as soon as possible.
Thank you in advance for your consideration of my request.
Best regards
