what should I do married to US citizan?

Your husband may be able to sponsor you for U.S. permanent resident status.  This is a two stage process starting with filing I-130 paperwork through a CIS Service Center in the U.S. and then processing for your immigrant visa through the U.S. Consulate abroad. the first step is For your husband to file I-130 paperwork here in the U.S.  See: http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=c67c7f9ded54d010VgnVCM10000048f3d6a1RCRD&vgnextchannel=db029c7755cb9010VgnVCM10000045f3d6a1RCRD  After an immigrant petition (family-based or employment-based) filed in the United States is approved by ISIS, and the petition requested immigrant visa processing, it is forwarded to the U.S. Department of State's National Visa Center (NAVIG) for processing. The NAVIG has a significant role in the next steps of the immigrant visa process by providing instructions to petitioners, sponsors, and visa applicants throughout the documentation gathering; reviewing required Affidavit of Support forms from sponsors to ensure compliance; and receiving fees, application forms, and other required documents from visa applicants. Upon receipt of the approval notice from ISIS, the National Visa Center will send an acknowledgement to the beneficiary that the approval notice has been received by the National Visa Center.  See: http://www.familytousa.com/immigrant-visa-processingconsu/ You should have your husband consult with an experienced immigration attorney to discuss the green card process.
