I am an American citizen(American passport)and I am working for Swiss/German Chemical company. I would like to apply for a business 1 year , multiple entry visa, (I have one on my passport for China but it has now expired last year, (I obtained it in US)). I have my letter of invitation from Tianjin now. I will be travelling between our offices in Tinjin and Guangzhou.
Can I make this request in Germany or will I have to send my passport back to Chinese embassy in US?
I am now in Stuttgart.
Thank you for your assistance.
