If wife and you both Chinese, probably not any real problem at all. Your income is sufficient and she's been here 6 years already. Only stumbling block may be short length of marriage. Usually want to see 2 years married. But as she's been here working for 6 years, may not make any difference. I think your chances are very good.
SOME PEOPLE TRY TO TURN BACK THEIR ODOMETERS. NOT ME. I WANT PEOPLE TO KNOW WHY I LOOK THIS WAY. I'VE TRAVELED A LONG WAY, AND SOME OF THE ROADS WEREN'T PAVED. ~ Will Rogers
