I'm trying to switch from my current L visa to a 6 month or one year F visa... but I have a Philippine passport so it's proven to be very difficult. I've called a bunch of agencies; some have simply refused to process Philippine passports and others are charging me 7 to 8 thousand kuai, which seems ridiculously high.
Does anyone know any agency where I could get it done for cheaper? In Hong Kong I could get a 6 month F visa for 5,000RMB, but I don't really want to fly there.
I can provide all the documents necessary, like business license and invitation letter. Isn't that all you need?
I'd appreciate any contacts anyone has that could possibly help me, or any more information on this.
