My GF and I have been dating 8 mo. 50% her time in U.S. & China on her Biz visa. She's pregnant. My baby. What visa now? How to we marry for the baby?

You appear to be very concerned about the money that will be involved with the baby being born in the US without insurance. That being the case, and unless you are dead set on having the baby born here, perhaps it is better that the baby be born in China. I assume that you can marry at any time, perhaps even now, and then begin the I-130 petition process with the idea of a final interview at the American consulate in Guangzhou.  Such would probably take about a year. That would likely give enough time for your wife to give birth and recover so that she would be able to gather the documentation and appear for an immigrant visa interview overseas. The timing should also give you time to prepare for a life with your wife and the child.
