can ichange my M1 to any other category?

You may be able to request a change of status. You need to act quickly as a change of status must be filed prior to the expiration of your current status. The nonimmigrant status you should seek will depend upon the reason why you wish to remain in the U.S. and your long-term immigration goals.
