I thought I'd start this thread so that everyone could write down the red tape they had to produce to get a visa extension in Kunming. Hopefully it will save someone some of the pointless time wasting I seem to have to go through every time.
I have an L class visa, I'm married to a Chinese national and we own a small apartment in Kunming.
My original L class 90 day visa was issued by the Chinese consulate in Sydney, Australia. This involved me filling out a piece of paper sticking on a passport photo and handing over my passport, which I then picked up - with visa a week later.
Last week I went in to the visa office in Beijing Lu to get a 90 day extension. Ended up going back and forth 3 times to get some new piece of paper, which they had neglected to tell me I needed on the previous trip. Would have been 4 times if I hadn't decided to bring the originals in with me just in case they decided they needed more copies.
If you are in similar circumstance to me you will need the following:
1. Copy of face page and visa page of your passport plus original.
2. Copy of your 'Registration voucher of residence for visitors from overseas' ( this is issued to you when you report to your local police station within 24 hours of arrival) plus original.
3. Copy of the filled in pages of your Household Register plus original.
4. Copy of your wife's/husbands Chinese ID card plus original. Your partner's Chinese passport cannot be used instead.
5. Copy of the filled in pages of your marriage book plus original.
6. Filled in visa application form with standard colour passport photo firmly affixed.
Most of this paperwork has been presented to them many times before and it is all in their computer files, but they still need you to present new copies every time.
They don't have a copy machine for use in the office and there's no copy shops close by, so don't forget to get copies made before you go in.
The cost is 160rmb for the 90 day extension. A 1 year extension costs 400rmb. You pay when you pick up, so don't forget to ask how much it costs, because they won't tell you if you don't ask and if you don't have enough cash on you when you go to pick up, they won't give you your passport back on a promise to pay the rest later. I believe the cost of the visa will also vary depending on the nationality of your passport.
