Ron, please don't give incorrect information!
Poster: with a K-1 visa, there is ABSOLUTELY NO WAY TO CHANGE STATUS!!! It is a one-way 'ticket' to the US for the SOLE purpose of getting married TO THE PETITIONER and adjusting status on that basis. There is no other possibility now or in the future. If you did not get married, go back to your home country before the I-94 expires and you fall out of status. After that happens and you accrue more than 180 days of unlawful presence, you will be barred from reentry to the US for 10 years even if you do find another basis for coming to the US.
If it did not work out, it's ok. These things happen. But don't let that experience ruin your chances of ever returning to the US lawfully.
