You did not mention if you are already a permanent resident or not. You must be a permanent resident of the U.S. for three years, if married to a U.S. citizen, before you can apply for U.S. citizenship. This process can be completed without a lawyer, but I strongly recommend that consult a local immigration attorney before you begin this process. You can also find more information on the USCIS website: www.uscis.gov
Good luck,
