I plan to move with girl I love. How do I move in with her

Hi, your girl is Chinese, right? you can apply a L visa with a duration of 30 days. If you intend to stay with her longer, you can apply an extension at the local PSB once about a week before the 30 days expires. If you get married with a Chinese, you may got 1 year multiple visa.

To remind you, you can find a job in China, and apply a Z visa, with which you can get a resident permit with a duration of one year.
