My boyfriend and i r getting married, hez an us citizen and im not...wat can we do?

You are an illegal alien. Marrying your boyfriend does NOT make you a US citizen or even a legal resident. You need to consult an immigration lawyer, as the way to become a legal resident is complicated. Many people spend years and a lot of money becoming legal. You'll probably need to go back to the country where you are a legal citizen, and go on from there.
