Comparing our experience to that of what we've been through applying for two unsuccessful tourist visas in Chengdu, we give the new Consulate in Guangzhou two thumbs way, way up. The staff is friendly and patient. The lines outside the consulate are well-organized before the doors ever open on interview mornings; line-jumping is also kept to an absolute minimum (somehow!), which for those of you in China will find very comforting.
The VO who interviewed my wife was very nice and treated my wife with the respect she needed to feel confident during the interview -- something seriously lacking at the Chengdu consulate. The process was a very smooth one for us. And for anyone else applying for immigration in Guangzhou, we urge you to relax and stay positive. It felt to us like everyone in the building was there to help.
