What a shame! If you want to stay at a country that you think is better for you and your family, please seek the right way. Otherwise, you have hurt thousands and thousands of innocent Chinese children who want to visit U.S.A just for some experiences and will return to China punctually. You are so selfish.
Besides, are you so comfortable with the made-up reason of "fear of being affected by One-Child-One-Family policy"? Will you feel at ease by seeking the green-card in such indecent means?
Shame on those who stay in other countries illegally. If you stay in one country legally, you can have education, work, decent life so long as you make efforts and you are smart. If you stay in one country illegally, you have closed your own door to all this. You can only wash dishes, fearing all days of being expelled out of the country, making your life a mess, a nightmare.
