About K 1 visa to the United States

Question 1: You and your boyfriend were not married locally in the United States, so if your child was not born in the United States, you can't get an American hukou. If your child was born in China, it will be classified as China nationality at birth.

Question 2: The fastest visa is a tourist visa. You can ask your boyfriend to sponsor you, but there is no guarantee that you will approve it or not. Because you are pregnant, the US Immigration Service will consider this issue very carefully.

Question 3: Because you are not married and have no American status, it is impossible to apply for priority treatment, because no matter which country's immigration office will allow foreigners to have children in their own country for no reason and take their own nationality.

So the only way now is to get a tourist visa to the United States and then extend it there. This is the only way.
