My partner and I want to get married so she can get her green card here in Kansas (USA) what's the fastest way to do it asap she's from Canada?

Is your partner currently in the United States? If so, when did she enter? When did you decide to marry? If your partner is not in the United States, you would need to file a fiancé visa petition on her behalf. This visa would allow her to enter the United States with the intent to marry and seek a green card. Entering on another nonimmigrant visas and with the intent to marry can lead to other adverse consequences.
