the two most important things are availability of funds and ties to home country. it seems you have the funds. so in terms of ties to home country i think first you can show an employment letter to show that you shall leave the USA. but also if you can show ties to your home country where you are from like ownership of land, property, have family or business commitments etc.
and with the american embassy it's all about how you present yourself so you need to prepare yourself for the interview and be confident and have supporting docs for it. there's a very helpful sight called path2usa.com which has alot of help with letting applicants know what kind of supporting docs are being looked for. wish you all the best.
