license duration is 30 years,in 30 years anytime u can use it to apply work visa.after getting work visa without spending money apply again every year ,just renewal.

Friends of foreigners coming to China. For your stable development in China, I hope you can hurry up to handle the work endorsement during the epidemic. After the epidemic, you will be able to get the work endorsement and secure work. Student visa can change the work endorsement. Tourist visa can change the work endorsement. Business visa can change the work endorsement. There is no need for bachelor's degree to handle the files . no working experience is needed. You can get the job endorsement smoothly. The faster the better.
Otherwise, your endorsement will expire after the outbreak. It's too late to handle it. The cost of your return home is too high, causing unnecessary losses.wechat 13269115653
