How can I get married in China with my boyfriend who has an American green card status, and then how can I apply for a visa to the United States as soon as possible?

First of all, your boyfriend is not a citizen,

So get married in China, apply slowly,

You can be naturalized after getting a green card for 5 years, and then apply for your marriage visa. There is no need to schedule it, which is estimated to be around 1 year.

You can do it quickly,

If you can go there as a tourist and have a baby with him in the United States after dark, the child will become an American citizen, and then apply for exemption from the lawyer. But this method is risky.

The quickest and safest way, you can see if this man is really good to you:

Let your boyfriend join the army, because the United States is at war now, and people without green cards and visas can apply for green cards quickly; Green card holders can apply for naturalization quickly; Citizens can quickly apply for family immigration or unmarried visas; Approve service sacrifice immediately. These approval procedures are attended by the military. The specific policies can be viewed on the website of the US Immigration Service, which is a bit like the firewire joining the Party in China War. It can be called firewire naturalization and firewire immigration. In a word, you can definitely go to America soon on this road, and it's hard to say what will happen to your boyfriend. In fact, the casualties of American troops in wartime are very low and very safe.
