We have been invited to Shanghai - we will travel from USA. We, my partner and I are private tutors teaching english to several students. Our benefactor is a resident Chinese Business woman. She is providing housing for us. We will travel in and out of the country 2-4 times a year. We both have a passport, but are not sure which visa application we need or where and when we should apply. We are to leave in January 2010.

Thank you, Kay
