If you entered the US unlawfully, under the current immigration laws, you will not be able to legalize your status within the US even if you get married to a US citizen. You will need to go back to your home country but as soon as you depart the US, you will automatically trigger a 10 year bar to reentry, which can only be waived by a showing of extreme hardship to a US citizen spouse, which is fairly difficult to do in most cases.
