visa for india passport holder but permanent resident in Japan

Hi, if you will work in the customer showroom in mainland China, you can apply for a work Z type for that. You should first prepare those documents including your passport and copy of its data page, a completed application form, a recently-taken passport-style photo, residence permit in Japan, and the employment permit. Then, submit the application to the CVASC.

hello i don't work there
he is my customer he bought brand new Porsche from my company and that why i want to visit his showroom for make more good deals
then i will come back to japan

Then you can apply for a tourist L type for that, and a business M type will also be fine.

Thank you for your kindly advice
