I am looking to marry a Chinese person who was not born in mainland China or India.
If I apply for a U.S. Green Card based on my own priority date, I would have to wait an extra three years; however, if I use my spouse's priority date, I could obtain it in about four years.
The key requirement is simply that the person was not born in mainland China; it is not a matter of nationality.
If you have the necessary documents, I can sign them for you, and we can get our green cards together.
