Changing Temporary Visa for Permanent Residence
I have an L type good for 6 months and renewable every 6 months. My wife is Chinese and is a permanent resident of China. Her and her brother started a consulting company and want to hire me as the Chief Consultant for the company because I have been providing technical consultancy to Chinese manufacturing companies since 2005 travel between USA and China every 6 months previously.
I have been living in Nanning, Guangxi, China since 2010 with my wife and during that time I previously had an F type, so I had to constantly leave China every 60 days, until I decided to change it to an L type to allow me to stay 6 months instead 60 days with multiple entries.
I want to change my L type for a Permanent Residence or get a Temporary one for longer than 1 year, e.g., 3 or years. Preferably permanent. How can I do this based on what I explained above.
