Try to change your lawyer early if you found he/she is not good. I think you lose some money right now is better than you lose your immigration case finally . I had experience with bad lawyer who name is Yieh Mao-shen in Houston. You could not get him by phone or e-mail after you paid money. He did nothing for me. He is a real "Xi Xue Gui"!
