my points

1. you do not care the lawyer's own english, do you? you are free to go for a native speaker, right? but you are then afraid there may be some communication problems from your side. hahaha

2. I think people who hire YIMINDIY because they want to have a Chinese-speaking advisor on their GC application.

3. Currently he is in China, but I can contact his (temporary) assistant now to work on my case.

4. I do not understand your last point very well. Do you think it is good or not that you can talk directly to the attorney?
