Country of birth ( not naturalized citizenship) determines wait times.
A B1 visa entry is for work of specific types. B2 visa entry is for visiting. Once you marry, you will be required to reply properly to any immigration form or officials questions regarding your relationship to your husband. It is possible that your application for entry at the border will be denied as it should be since you have admitted on a public forum that it is not your intent to "visit" but to "stay" - i.e. live in violation with the terms of your admission if on B2.
If you do not want a long distance marriage, he will need to arrange to live with you in a country where you both may live. Alternatively, postpone your marriage until he obtains his citizenship and can sponsor you as an immediate relative. He can give up his US green card and move to India to be with you permanently which he would gladly do and you would welcome if the relationship were more important than the green card.
There are no shortcuts to US permanent residency. If there were, there are far more people with more compelling stories than yours. You are not even married and want to get to the front of the line when many tens of thousands of people have been separated from their family for many years already. They are waiting patiently and not trying to scam the system by obtaining citizenship in a third country that they have no intent of using.
