hi im living in china and i want to marry my chinese girlfriend. i came on a one year work visa, which in now over and has been changed to a one month tourist visa. my visa expires in about 3 weeks. if we get married, and i have all the correct documents will they extend my visa without me leaving china or will i have to go home and come back? is it possible to go to hong kong apply for the family/ spouse visa and then return to mainland china? thank you
