Im on my first entry and I am running out of days. I do not want to travel out of China to obtain my second entry. Is it possible to extend my first entry at the Visa office in Kunming?

I know it is possible to extend any standard 1 entry visa by 2 single months as I have done it before. Im just unsure about the double entry visa, especially as I am only on my first entry.

Any advice is good

Thanks.

I have in the past renewed a double entry visa here in Kunming, but you will lose your second entry and will just get the usual extra 30 days.

I renewed a double entry here in Kunming. Lost the second entry (cancelled the existing visa) like ludwig said, but was extended for 6 months with 1 entry so in the end I didn't really loose anything.
