Can please you update on the results of the HK trip? I have a similar headache with F-visa. Thanks.
Basically what I said above is what happened. I went down to HK in late June and got a one month single entry L (entry valid for 3 months, but I entered the same day). I was told I could also get a double entry L, but since I can extend in China without leaving the country (each stay on the double entry L is limited to 30 days) I didn't see a point in getting a double entry, especially considering the fact that I planned to stay here continuously for about 50 days.
As I mentioned above, the travel agent also told me that if I'd been able to show the previous evidence of F visas (my old passport with the F visas being in the U.S.) I'd be eligible for another F visa, but I think it would have 30 day stay limitations.
The travel agent also informed me that PRC visas for American and British citizens could not be processed on Saturday, as was done previously and I suppose is still ok for other nationalities. This may be because the multiple entry F visas we were getting earlier were from Guangdong (even though I gave it to the agent in HK), and the L visa they processed for me was from Hong Kong. Not sure.
That was a little over a month ago, but I believe the situation is the same now. I just extended my L visa last week at Wusong Lu for one month. RMB 160, no questions asked, but took 3 days to process.
Hope this is of some help.
