1. United action. For example, if we send letters to the Congress, we should send our individule letters together, or, sign a representative letter together. If resort to law or constitution, we should donate to our representatives together.
2. Logic. Some excellent sample letters have already been posted in this forum. DOS/USCIS may explain that they had a good intention to improve immigration service by doing so and so (such as memo, indian visa number availability), because it seems to move in a positive direction. But, why it always turns out to be adversed to the majority of Chinese employment-based immigration applicants? This they never explain, but they should explain. Asking questions would be easier for us (no mistake could be made or caught by just asking questions) but would be more difficult for them (if no fair answers could be given, we then move to the next step) So, ask first, charge later.
3. Unit with also indian rather than isolate ourselves.
Let's think and act.
